macOS Compatibility for TCP Server

This pull request adds cross-platform support for macOS while maintaining Linux compatibility.

Changes Made:

1. Platform-Specific Headers:

   • Added conditional includes for Linux-specific headers (asm-generic/socket.h, endian.h, etc.)
   • Added macOS alternatives using the appropriate includes

2. File Watcher Implementation:

   • Modified the file watcher to work on both platforms
   • Linux version uses inotify API
   • macOS version uses a polling-based approach

3. Socket Options:

   • Fixed SO_REUSEPORT socket option that's not compatible with macOS
   • Used platform-specific socket option settings

4. Documentation:

   • Updated README with macOS installation instructions
   • Added notes about platform-specific implementations

Testing:

All features have been tested on macOS and are working correctly:

• HTML templating functions properly
• WebSocket connections establish correctly
• Hot reload feature works when modifying HTML files

These changes make the project truly cross-platform without sacrificing any functionality.
