robobun 33fdc2112f feat: add --cpu and --os flags to bun install for filtering optional dependencies (#22850) ...

## Summary

Implements `--cpu` and `--os` flags for `bun install` to filter optional
dependencies based on target architecture and operating system. This
allows developers to control which platform-specific optional
dependencies are installed.

## What Changed

### Core Implementation
- Added `--cpu` and `--os` flags to `bun install` command that accept
multiple values
- Multiple values combine with bitwise OR (e.g., `--cpu x64 --cpu arm64`
matches packages for either architecture)
- Updated `isDisabled` methods throughout the codebase to accept custom
CPU/OS targets
- Removed deprecated `isMatch` methods in favor of `isMatchWithTarget`
for consistency

### Files Modified
- `src/install/npm.zig` - Removed `isMatch` methods, standardized on
`isMatchWithTarget`
- `src/install/PackageManager/CommandLineArguments.zig` - Parse and
validate multiple flag values
- `src/install/PackageManager/PackageManagerOptions.zig` - Pass CPU/OS
options through
- `src/install/lockfile/Package.zig` & `Package/Meta.zig` - Updated
`isDisabled` signatures
- `src/install/lockfile/Tree.zig` & `lockfile.zig` - Updated call sites

## Usage Examples

```bash
# Install only x64 dependencies
bun install --cpu x64

# Install dependencies for both x64 and arm64
bun install --cpu x64 --cpu arm64

# Install Linux-specific dependencies
bun install --os linux

# Install for multiple platforms
bun install --cpu x64 --cpu arm64 --os linux --os darwin
```

## Test Plan

✅ All 10 tests pass in `test/cli/install/bun-install-cpu-os.test.ts`:
- CPU architecture filtering
- OS filtering
- Combined CPU and OS filtering
- Multiple CPU architectures support
- Multiple operating systems support
- Multiple CPU and OS combinations
- Error handling for invalid values
- Negated CPU/OS support (`!arm64`, `!linux`)
