- Added `socket2` dependency for socket options. - Introduced `keep_alive`, `keep_alive_initial_delay_ms`, and `max_connections` fields in `ConnectionConfig`. - Implemented TCP keepalive settings in `TcpListenerManager` for both client and backend connections. - Created a new `ConnectionPool` for managing idle HTTP/1.1 and HTTP/2 connections to reduce overhead. - Enhanced TLS configuration to support ALPN for HTTP/2. - Added performance tests for connection pooling, stability, and concurrent connections.
