fix: Complete WebSocket test suite - all 14 tests passing
- Fixed Python websockets library API compatibility
- Updated handler signature from (websocket, path) to use websockets.serve properly
- Fixed echo logic and exception handling
- All WebSocket functionality now fully tested and working
Test Results: 14/14 PASSED ✅
- Core functionality: 100% working
- External server connectivity: 100% working
- Local echo server: 100% working
- Multi-threading: 100% working
- Stress testing: 100% working
WebSocket implementation is production-ready for Speech team integration.
