feat: Add @prettier/plugin-oxc for faster formatting (#6088)

Note for reviewers: the code changes in src/* is because I've upgraded
prettier to latest.

the @prettier/plugin-oxc it self only improve performance and doesnt
affect format rules

## Summary

Integrates `@prettier/plugin-oxc` to improve Prettier performance by
~20%.

The oxc plugin provides a faster parser written in Rust, significantly
speeding up formatting operations across the codebase.

## Changes

- Added `@prettier/plugin-oxc` as dev dependency
- Updated `.prettierrc` to use oxc plugin alongside existing
sort-imports plugin
- Added `scripts/benchmark-prettier.js` to measure performance
improvements
- Updated `knip.config.ts` to ignore the oxc plugin
- Updated `eslint.config.ts` to ignore the benchmark script

## Benchmark Results

Ran 3 benchmarks comparing formatting performance on the entire
codebase:

**Without oxc:**
- Median: 32.76s
- Average: 32.89s
- Min: 32.49s
- Max: 33.43s

**With oxc:**
- Median: 26.13s
- Average: 26.35s
- Min: 25.24s
- Max: 27.69s

**Improvement: 20.26% faster (6.64s saved)**

## Testing

The benchmark script can be run with:
```bash
node scripts/benchmark-prettier.js
```

This will:
1. Test formatting performance without oxc plugin
2. Test formatting performance with oxc plugin
3. Display comparison results
4. Restore original configuration
