Add complete C implementation of wssshd (wssshd2)

- Full WebSocket protocol implementation from scratch (RFC 6455) - SSL/TLS encryption with automatic certificate generation - Client registration and authentication system - Tunnel request processing and forwarding - Terminal/PTY session management - HTTP web interface with embedded assets - Multi-threaded concurrent connection handling - Memory-safe implementation with proper resource management - Compatible with existing wssshc/wsssht clients - Self-contained binary (42KB) vs Python version (10MB+)
