feat(bundler): support optional chaining and import.meta.env in env:inline

- Allow `process?.env?.VAR` and `process?.env?.["VAR"]` to be inlined
  when using `env:inline` in bun.build. This matches esbuild's behavior
  for define matching with optional chain expressions.

- Add `import.meta.env.*` inlining for Vite compatibility. Environment
  variables are now exposed via both `process.env.*` and `import.meta.env.*`
  when using `env:inline` or prefix patterns like `VITE_*`.

- Add define checking for e_index (bracket notation) with optional chains
  to ensure `process?.env?.["VAR"]` patterns work correctly.

 ## How It Works
 
 Bun uses `HTMLRewriter` to scan for `<script>` and `<link>` tags in HTML files, uses them as entrypoints for Bun's bundler, generates an optimized bundle for the JavaScript/TypeScript/TSX/JSX and CSS files, and serves the result.

-The `feature()` function is replaced with `true` or `false` at bundle time. Combined with minification, unreachable code is eliminated:

-```
-

-var mode = "premium";
-```
-
-```js title="Output (without --feature PREMIUM, with --minify)" icon="/icons/javascript.svg"
-var mode = "free";
-```
-
-**Key behaviors:**
-
-- `feature()` requires a string literal argument — dynamic values are not supported
-- The `bun:bundle` import is completely removed from the output
-- Works with `bun build`, `bun run`, and `bun test`
-- Multiple flags can be enabled: `--feature FLAG_A --feature FLAG_B`
-- For type safety, augment the `Registry` interface to restrict `feature()` to known flags (see below)
-
-**Use cases:**
-
-- Platform-specific code (`feature("SERVER")` vs `feature("CLIENT")`)
-- Environment-based features (`feature("DEVELOPMENT")`)
-- Gradual feature rollouts
-- A/B testing variants
-- Paid tier features
-
-**Type safety:** By default, `feature()` accepts any string. To get autocomplete and catch typos at compile time, create an `env.d.ts` file (or add to an existing `.d.ts`) and augment the `Registry` interface:
-
-```ts title="env.d.ts" icon="/icons/typescript.svg"
-declare module "bun:bundle" {
-  interface Registry {
-    features: "DEBUG" | "PREMIUM" | "BETA_FEATURES";
-  }
-}
-```
-
-Ensure the file is included in your `tsconfig.json` (e.g., `"include": ["src", "env.d.ts"]`). Now `feature()` only accepts those flags, and invalid strings like `feature("TYPO")` become type errors.

-
-// Keep event loop alive while terminal is open
-proc.terminal.ref();
-proc.terminal.unref();
-
-// Close the terminal
-proc.terminal.close();
-```
-
-### Reusable Terminal
-
-You can create a terminal independently and reuse it across multiple subprocesses:
-
-```ts
-await using terminal = new Bun.Terminal({
-  cols: 80,
-  rows: 24,
-  data(term, data) {
-    process.stdout.write(data);
-  },
-});
-
-// Spawn first process
-const proc1 = Bun.spawn(["echo", "first"], { terminal });
-await proc1.exited;
-
-// Reuse terminal for another process
-const proc2 = Bun.spawn(["echo", "second"], { terminal });
-await proc2.exited;
-
-// Terminal is closed automatically by `await using`
-```
-
-When passing an existing `Terminal` object:
-
-- The terminal can be reused across multiple spawns
-- You control when to close the terminal
-- The `exit` callback fires when you call `terminal.close()`, not when each subprocess exits
-- Use `proc.exited` to detect individual subprocess exits
-
-This is useful for running multiple commands in sequence through the same terminal session.
-
-<Note>Terminal support is only available on POSIX systems (Linux, macOS). It is not available on Windows.</Note>

 ## Blocking API (`Bun.spawnSync()`)
 
 Bun provides a synchronous equivalent of `Bun.spawn` called `Bun.spawnSync`. This is a blocking API that supports the same inputs and parameters as `Bun.spawn`. It returns a `SyncSubprocess` object, which differs from `Subprocess` in a few ways.

-The type parameter `<undefined>` represents WebSocket data — if you add a `websocket` handler with custom data attached via `server.upgrade(req, { data: ... })`, replace `undefined` with your data type.
-
 Instead of passing the server options into `Bun.serve`, `export default` it. This file can be executed as-is; when Bun sees a file with a `default` export containing a `fetch` handler, it passes it into `Bun.serve` under the hood.

 <Note>
-**What does "cached" mean?**
+ Use the `.prepare()` method to prepare a query _without_ caching it on the `Database` instance.
 
-The caching refers to the **compiled prepared statement** (the SQL bytecode), not the query results. When you call `db.query()` with the same SQL string multiple times, Bun returns the same cached `Statement` object instead of recompiling the SQL.
-
-It is completely safe to reuse a cached statement with different parameter values:

-const query = db.query("SELECT * FROM users WHERE id = ?");

-query.get(2); // ✓ Also works - parameters are bound fresh each time
-query.get(3); // ✓ Still works

-Use `.prepare()` instead of `.query()` when you want a fresh `Statement` instance that isn't cached, for example if you're dynamically generating SQL and don't want to fill the cache with one-off queries.

- *
- * # At runtime
- * bun run --feature=SUPER_SECRET index.ts
