1.6.6 : Version Compatibility, Reconnect Stability & Test Coverage

[NytroxDev]

Added

• Version class + COMPATIBILITY table : declarative per-version wire compatibility policy
• GitHub Actions CI : version consistency check, test matrix on Python 3.8–3.14
• +111 new tests (compatibility, client tags, clients_manager, utils, sender, error handling, reconnect)

Changed

• Handshake version check refactored to use Version + COMPATIBILITY table
• Reconnect tests rewritten : polling helpers, dynamic ports, no more 30s timeouts

Fixed

• ThreadingSocket._create_client_instance() missing client_manager : server never closed client sockets, disconnect relied on GC (2–3s random delay)
• ReconnectHandler.reconnect_loop() : retry delay applied before every attempt instead of between failures
• ReconnectHandler.stop_retry() : time.sleep() wasn't interruptible; replaced with threading.Event.wait()
• ThreadingSocket.close_all() : listening socket closed after client connections, allowing phantom reconnects; now closes listener first
• Server.close_client(id_=0) : falsy id_ check, now uses is not None
• ThreadingSocket.bind() : returns bool instead of None
