Introduce Bun.secrets API (#21973)

This PR adds `Bun.secrets`, a new API for securely storing and
retrieving credentials using the operating system's native credential
storage locally. This helps developers avoid storing sensitive data in
plaintext config files.

```javascript
// Store a GitHub token securely
await Bun.secrets.set({
  service: "my-cli-tool",
  name: "github-token",
  value: "ghp_xxxxxxxxxxxxxxxxxxxx"
});

// Retrieve it when needed
const token = await Bun.secrets.get({
  service: "my-cli-tool",
  name: "github-token"
});

// Use with fallback to environment variable
const apiKey = await Bun.secrets.get({
  service: "my-app",
  name: "api-key"
}) || process.env.API_KEY;
```

Marking this as a draft because Linux and Windows have not been manually
tested yet. This API is only really meant for local development usecases
right now, but it would be nice if in the future to support adapters for
production or CI usecases.

### Core API
- `Bun.secrets.get({ service, name })` - Retrieve a stored credential
- `Bun.secrets.set({ service, name, value })` - Store or update a
credential
- `Bun.secrets.delete({ service, name })` - Delete a stored credential

### Platform Support
- **macOS**: Uses Keychain Services via Security.framework
- **Linux**: Uses libsecret (works with GNOME Keyring, KWallet, etc.)
- **Windows**: Uses Windows Credential Manager via advapi32.dll

### Implementation Highlights
- Non-blocking - all operations run on the threadpool
- Dynamic loading - no hard dependencies on system libraries
- Sensitive data is zeroed after use
- Consistent API across all platforms

## Use Cases

This API is particularly useful for:
- CLI tools that need to store authentication tokens
- Development tools that manage API keys
- Any tool that currently stores credentials in `~/.npmrc`,
`~/.aws/credentials` or in environment variables that're globally loaded

## Testing

Comprehensive test suite included with coverage for:
- Basic CRUD operations
- Empty strings and special characters
- Unicode support
- Concurrent operations
- Error handling

All tests pass on macOS. Linux and Windows implementations are complete
but would benefit from additional platform testing.

## Documentation

- Complete API documentation in `docs/api/secrets.md`
- TypeScript definitions with detailed JSDoc comments and examples

+Store and retrieve sensitive credentials securely using the operating system's native credential storage APIs.
+
+**Experimental:** This API is new and experimental. It may change in the future.
+
+```typescript
+import { secrets } from "bun";
+
+const githubToken = await secrets.get({
+  service: "my-cli-tool",
+  name: "github-token",
+});
+
+if (!githubToken) {
+  const response = await fetch("https://api.github.com/name", {
+    headers: { "Authorization": `token ${githubToken}` },
+  });
+  console.log("Please enter your GitHub token");
+} else {
+  await secrets.set({
+    service: "my-cli-tool",
+    name: "github-token",
+    value: prompt("Please enter your GitHub token"),
+  });
+  console.log("GitHub token stored");
+}
+```
+
+## Overview
+
+`Bun.secrets` provides a cross-platform API for managing sensitive credentials that CLI tools and development applications typically store in plaintext files like `~/.npmrc`, `~/.aws/credentials`, or `.env` files. It uses:
+
+- **macOS**: Keychain Services
+- **Linux**: libsecret (GNOME Keyring, KWallet, etc.)
+- **Windows**: Windows Credential Manager
+
+All operations are asynchronous and non-blocking, running on Bun's threadpool.
+
+Note: in the future, we may add an additional `provider` option to make this better for production deployment secrets, but today this API is mostly useful for local development tools.
+
+## API
+
+### `Bun.secrets.get(options)`
+
+Retrieve a stored credential.
+
+```typescript
+import { secrets } from "bun";
+
+const password = await Bun.secrets.get({
+  service: "my-app",
+  name: "alice@example.com",
+});
+// Returns: string | null
+
+// Or if you prefer without an object
+const password = await Bun.secrets.get("my-app", "alice@example.com");
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+
+**Returns:**
+
+- `Promise<string | null>` - The stored password, or `null` if not found
+
+### `Bun.secrets.set(options, value)`
+
+Store or update a credential.
+
+```typescript
+import { secrets } from "bun";
+
+await secrets.set({
+  service: "my-app",
+  name: "alice@example.com",
+  value: "super-secret-password",
+});
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+- `value` (string, required) - The password or secret to store
+
+**Notes:**
+
+- If a credential already exists for the given service/name combination, it will be replaced
+- The stored value is encrypted by the operating system
+
+### `Bun.secrets.delete(options)`
+
+Delete a stored credential.
+
+```typescript
+const deleted = await Bun.secrets.delete({
+  service: "my-app",
+  name: "alice@example.com",
+  value: "super-secret-password",
+});
+// Returns: boolean
+```
+
+**Parameters:**
+
+- `options.service` (string, required) - The service or application name
+- `options.name` (string, required) - The username or account identifier
+
+**Returns:**
+
+- `Promise<boolean>` - `true` if a credential was deleted, `false` if not found
+
+## Examples
+
+### Storing CLI Tool Credentials
+
+```javascript
+// Store GitHub CLI token (instead of ~/.config/gh/hosts.yml)
+await Bun.secrets.set({
+  service: "my-app.com",
+  name: "github-token",
+  value: "ghp_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Or if you prefer without an object
+await Bun.secrets.set("my-app.com", "github-token", "ghp_xxxxxxxxxxxxxxxxxxxx");
+
+// Store npm registry token (instead of ~/.npmrc)
+await Bun.secrets.set({
+  service: "npm-registry",
+  name: "https://registry.npmjs.org",
+  value: "npm_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Retrieve for API calls
+const token = await Bun.secrets.get({
+  service: "gh-cli",
+  name: "github.com",
+});
+
+if (token) {
+  const response = await fetch("https://api.github.com/name", {
+    headers: {
+      "Authorization": `token ${token}`,
+    },
+  });
+}
+```
+
+### Migrating from Plaintext Config Files
+
+```javascript
+// Instead of storing in ~/.aws/credentials
+await Bun.secrets.set({
+  service: "aws-cli",
+  name: "AWS_SECRET_ACCESS_KEY",
+  value: process.env.AWS_SECRET_ACCESS_KEY,
+});
+
+// Instead of .env files with sensitive data
+await Bun.secrets.set({
+  service: "my-app",
+  name: "api-key",
+  value: "sk_live_xxxxxxxxxxxxxxxxxxxx",
+});
+
+// Load at runtime
+const apiKey =
+  (await Bun.secrets.get({
+    service: "my-app",
+    name: "api-key",
+  })) || process.env.API_KEY; // Fallback for CI/production
+```
+
+### Error Handling
+
+```javascript
+try {
+  await Bun.secrets.set({
+    service: "my-app",
+    name: "alice",
+    value: "password123",
+  });
+} catch (error) {
+  console.error("Failed to store credential:", error.message);
+}
+
+// Check if a credential exists
+const password = await Bun.secrets.get({
+  service: "my-app",
+  name: "alice",
+});
+
+if (password === null) {
+  console.log("No credential found");
+}
+```
+
+### Updating Credentials
+
+```javascript
+// Initial password
+await Bun.secrets.set({
+  service: "email-server",
+  name: "admin@example.com",
+  value: "old-password",
+});
+
+// Update to new password
+await Bun.secrets.set({
+  service: "email-server",
+  name: "admin@example.com",
+  value: "new-password",
+});
+
+// The old password is replaced
+```
+
+## Platform Behavior
+
+### macOS (Keychain)
+
+- Credentials are stored in the name's login keychain
+- The keychain may prompt for access permission on first use
+- Credentials persist across system restarts
+- Accessible by the name who stored them
+
+### Linux (libsecret)
+
+- Requires a secret service daemon (GNOME Keyring, KWallet, etc.)
+- Credentials are stored in the default collection
+- May prompt for unlock if the keyring is locked
+- The secret service must be running
+
+### Windows (Credential Manager)
+
+- Credentials are stored in Windows Credential Manager
+- Visible in Control Panel → Credential Manager → Windows Credentials
+- Persist with `CRED_PERSIST_ENTERPRISE` flag so it's scoped per user
+- Encrypted using Windows Data Protection API
+
+## Security Considerations
+
+1. **Encryption**: Credentials are encrypted by the operating system's credential manager
+2. **Access Control**: Only the name who stored the credential can retrieve it
+3. **No Plain Text**: Passwords are never stored in plain text
+4. **Memory Safety**: Bun zeros out password memory after use
+5. **Process Isolation**: Credentials are isolated per name account
+
+## Limitations
+
+- Maximum password length varies by platform (typically 2048-4096 bytes)
+- Service and name names should be reasonable lengths (< 256 characters)
+- Some special characters may need escaping depending on the platform
+- Requires appropriate system services:
+  - Linux: Secret service daemon must be running
+  - macOS: Keychain Access must be available
+  - Windows: Credential Manager service must be enabled
+
+## Comparison with Environment Variables
+
+Unlike environment variables, `Bun.secrets`:
+
+- ✅ Encrypts credentials at rest (thanks to the operating system)
+- ✅ Avoids exposing secrets in process memory dumps (memory is zeroed after its no longer needed)
+- ✅ Survives application restarts
+- ✅ Can be updated without restarting the application
+- ✅ Provides name-level access control
+- ❌ Requires OS credential service
+- ❌ Not very useful for deployment secrets (use environment variables in production)
+
+## Best Practices
+
+1. **Use descriptive service names**: Match the tool or application name
+   If you're building a CLI for external use, you probably should use a UTI (Uniform Type Identifier) for the service name.
+
+   ```javascript
+   // Good - matches the actual tool
+   { service: "com.docker.hub", name: "username" }
+   { service: "com.vercel.cli", name: "team-name" }
+
+   // Avoid - too generic
+   { service: "api", name: "key" }
+   ```
+
+2. **Credentials-only**: Don't store application configuration in this API
+   This API is slow, you probably still need to use a config file for some things.
+
+3. **Use for local development tools**:
+   - ✅ CLI tools (gh, npm, docker, kubectl)
+   - ✅ Local development servers
+   - ✅ Personal API keys for testing
+   - ❌ Production servers (use proper secret management)
+
+## TypeScript
+
+```typescript
+namespace Bun {
+  interface SecretsOptions {
+    service: string;
+    name: string;
+  }
+
+  interface Secrets {
+    get(options: SecretsOptions): Promise<string | null>;
+    set(options: SecretsOptions, value: string): Promise<void>;
+    delete(options: SecretsOptions): Promise<boolean>;
+  }
+
+  const secrets: Secrets;
+}
+```

+# Secrets API CI Setup Guide
+
+This guide explains how to run the `Bun.secrets` API tests in CI environments on Linux (Ubuntu/Debian).
+
+## Overview
+
+The `Bun.secrets` API uses the system keyring to store credentials securely. On Linux, this requires:
+- libsecret library for Secret Service API integration
+- gnome-keyring daemon for credential storage  
+- D-Bus session for communication
+- Proper keyring initialization
+
+## Automatic CI Setup (Recommended)
+
+The secrets test automatically detects CI environments and sets up everything needed:
+
+```bash
+# Just run the test normally - setup happens automatically!
+bun test test/js/bun/secrets.test.ts
+```
+
+The test will:
+1. **Detect CI environment** - Checks if running on Linux + Ubuntu/Debian in CI
+2. **Install packages** - Automatically installs required packages if missing
+3. **Setup keyring** - Creates keyring directory and configuration
+4. **Initialize services** - Starts D-Bus and gnome-keyring-daemon
+5. **Run tests** - Executes all secrets API tests
+
+## Manual CI Setup
+
+If automatic setup doesn't work, you can pre-install packages:
+
+```bash
+# Install packages in CI setup step
+apt-get update && apt-get install -y libsecret-1-dev gnome-keyring dbus-x11
+
+# Run tests normally
+bun test test/js/bun/secrets.test.ts
+```
+
+## Required Packages
+
+On Ubuntu/Debian systems, install these packages:
+
+```bash
+apt-get install -y \
+  libsecret-1-dev \   # libsecret development headers
+  gnome-keyring \     # GNOME Keyring daemon
+  dbus-x11           # D-Bus X11 integration
+```
+
+## Environment Variables
+
+The test automatically detects CI environments and sets up the keyring. You can force setup with:
+
+```bash
+FORCE_KEYRING_SETUP=1 bun test test/js/bun/secrets.test.ts
+```
+
+## How It Works
+
+1. **Detection**: Tests check if running on Linux + Ubuntu/Debian in CI
+2. **Packages**: Verify libsecret is available 
+3. **Directory**: Create `~/.local/share/keyrings/` directory
+4. **Keyring**: Create `login.keyring` file with empty password setup
+5. **Daemon**: Start `gnome-keyring-daemon` with login keyring
+6. **D-Bus**: Ensure D-Bus session is available for communication
+7. **Tests**: Run secrets tests which use the Secret Service API
+
+## Platform Support
+
+- ✅ **Linux (Ubuntu/Debian)**: Full support with automatic CI setup
+- ✅ **Linux (Other)**: Manual setup required (see above commands)
+- ⚠️  **macOS**: Uses macOS Keychain (different implementation)
+- ⚠️  **Windows**: Uses Windows Credential Manager (different implementation)
+
+## API Behavior
+
+### Empty String as Delete
+
+The `Bun.secrets.set()` method now supports deleting credentials by passing an empty string:
+
+```ts
+// These are equivalent:
+await Bun.secrets.delete({ service: "myapp", name: "token" });
+await Bun.secrets.set({ service: "myapp", name: "token", value: "" });
+```
+
+**Benefits:**
+- **Windows compatibility** - Required by Windows Credential Manager API
+- **Simplified workflows** - Single method for set/delete operations
+- **Batch operations** - Easy to clear multiple credentials in loops
+
+**Behavior:**
+- Setting an empty string deletes the credential if it exists
+- No error if the credential doesn't exist (consistent with `delete()`)
+- Returns normally (no special return value)
+
+### Unrestricted Access for CI Environments
+
+The `allowUnrestrictedAccess` parameter allows credentials to be stored without user interaction on macOS:
+
+```ts
+// For CI environments where user interaction is not possible
+await Bun.secrets.set({
+  service: "ci-deployment", 
+  name: "api-key",
+  value: process.env.API_KEY,
+  allowUnrestrictedAccess: true // Bypass macOS keychain user prompts
+});
+```
+
+**Security Considerations:**
+- ⚠️ **Use with caution** - When `allowUnrestrictedAccess: true`, any application can read the credential
+- ✅ **Recommended for CI** - Useful in headless CI environments like MacStadium or GitHub Actions
+- 🔒 **Default is secure** - When `false` (default), only your application can access the credential
+- 🖥️ **macOS only** - This parameter is ignored on Linux and Windows platforms
+
+**When to Use:**
+- ✅ CI/CD pipelines that need to store credentials without user interaction
+- ✅ Automated testing environments 
+- ✅ Headless server deployments on macOS
+- ❌ Production applications with sensitive user data
+- ❌ Desktop applications with normal user interaction
+
+## Troubleshooting
+
+### "libsecret not available"
+- Install `libsecret-1-dev` package
+- Verify with: `pkg-config --exists libsecret-1`
+
+### "Cannot autolaunch D-Bus without X11 $DISPLAY"  
+- Run tests inside `dbus-run-session` 
+- Set `DISPLAY=:99` environment variable
+
+### "Object does not exist at path '/org/freedesktop/secrets/collection/login'"
+- Create the login keyring file as shown above
+- Start gnome-keyring-daemon with `--login` flag
+
+### "Cannot create an item in a locked collection"
+- Initialize keyring with empty password: `echo -n "" | gnome-keyring-daemon --unlock`
+- Ensure keyring file has `lock-on-idle=false`
+
+## CI Configuration Examples
+
+### GitHub Actions
+```yaml
+- name: Run secrets tests (auto-setup)
+  run: bun test test/js/bun/secrets.test.ts
+```
+
+Or with explicit package installation:
+```yaml
+- name: Install keyring packages  
+  run: |
+    sudo apt-get update
+    sudo apt-get install -y libsecret-1-dev gnome-keyring dbus-x11
+
+- name: Run secrets tests
+  run: bun test test/js/bun/secrets.test.ts
+```
+
+### BuildKite
+```yaml
+steps:
+  - command: bun test test/js/bun/secrets.test.ts
+    label: "🔐 Secrets API Tests"
+```
+
+### Docker
+```dockerfile
+# Optional: pre-install packages for faster test startup
+RUN apt-get update && apt-get install -y \
+    libsecret-1-dev \
+    gnome-keyring \
+    dbus-x11
+
+# Run test normally - setup is automatic
+RUN bun test test/js/bun/secrets.test.ts
+```
