fix: resolve test hanging issue in CI

- Reduce CI reporters to prevent resource contention (removed json/html)
- Optimize coverage settings with all:false and skipFull:true
- Fix MSW waitForRequest memory leak by adding timeout and cleanup
- Add teardownTimeout to vitest config
- Add 10-minute timeout to GitHub Actions job
- Create emergency test script without coverage for debugging

The main issues were:
1. Coverage collection with multiple reporters causing exhaustion
2. MSW event listener that could hang indefinitely
3. Too many simultaneous reporters (4 at once)
