Adds optional tracker kwarg to SSHClientConnection.forward_local_port that accepts a ForwardTracker (typing.Protocol) with two hooks: connection_made(orig_host, orig_port) -> None connection_lost(orig_host, orig_port, exc) -> None The hooks fire on every client connect/disconnect on the local listener. Hook exceptions are swallowed so a buggy tracker cannot break the forwarder. Backward compatible: tracker defaults to None, preserving existing behavior with no overhead. Use case: passive observation of local-forward activity (idle-based auto-shutdown, byte counters, etc.) without modifying transport code.
