feat: cross-platform uSockets support and route cache optimization

1. Cross-platform uSockets configuration
   - Use @VMODROOT for portable library paths
   - Support macOS (arm64/x86_64), Windows, and Linux
   - Auto-detect Homebrew paths for libuv on macOS

2. Route cache optimization (3x performance boost)
   - Replace LRU cache with FastRouteCache for dynamic routes
   - Zero-overhead cache lookup (no TTL check, no LRU reordering)
   - Dynamic route performance: 30k -> 97k RPS

3. New test files
   - Go-based integration tests for picoev and uSockets
   - FastCache optimization validation tests
   - Benchmark comparison tools
