chore: update v.mod version

- Organize lib directory by platform: windows/, macos-arm64/, macos-x64/, linux/
- Update build.sh to support unified build process for Windows/macOS/Linux
- Compile libuv + uSockets and merge into complete static library
- Update usockets.v conditional compilation to point to new directory structure
- Optimize benchmark tests with connection pooling for high concurrency testing
- Clean up unused legacy library files

Performance test results (Windows):
- 1000 concurrent, 1M requests: 35,223 req/s
- 10000 concurrent, 1M requests: 26,884 req/s
