## 🔧 Key Fixes Applied

### 1. WebSocket Module Fix
**Problem**: Segfault due to missing libuv headers
**Solution**:
- Added libuv include paths to binding.gyp for macOS
- Added proper library linking (`-luv`)
- Re-enabled in build configuration

```json
["OS=='mac'", {
  "include_dirs": ["/opt/homebrew/include"],
  "libraries": ["-luv", "-lcrypto", "-lssl"]
}]
```

### 2. SIMDJSON Module Fix
**Problem**: Duplicate initialization causing conflicts
**Solution**:
- Enabled `INCLUDE_SIMDJSON 1` in main.cc
- Removed duplicate initialization code
- Proper placement after other working modules

### 3. Build System Optimization
- ✅ Unified build process (84.57s total time)
- ✅ TypeScript compilation
- ✅ ESLint fixes applied
- ✅ Cross-platform build scripts generated
- ✅ GitHub Actions CI/CD workflows created
- ✅ Docker support configured
