1.24.0

Added

• ConnectionCompat mixin in mixin.py extracting backward-compatible Connection delegation methods (socket, renable, is_restored(), enable_read(), etc.) from StreamProtocol
• ConnectionCompat applied to TransportStream so it exposes is_restored() and other throttle-related methods
• Throttle unit tests for proxy server covering both Connection and TransportStream paths

Changed

• StreamProtocol now inherits from ConnectionCompat mixin instead of defining delegation methods inline
• _throttle() in ProxyServer and SocksServer resolves TransportStream to its _protocol for conn_map key lookup

Fixed

• AttributeError: 'TransportStream' object has no attribute 'is_restored' in proxy throttle callbacks when using protocol-based architecture
