libhttp v3.1: - add ws_proxy(path, handshake) API with WsProxyHandshakeHandler callback - implement full-duplex async bidirectional bridging (text+binary frames) - support ws:// and wss:// backends with SNI, write queues for ordering - proxy routes take priority over regular ws() routes - 403 response on handshake rejection, graceful close propagation gateway v0.6.0: - add [WsProxy] config section (routes = /path=ws://backend;...) - handshake callback verifies Token (Authorization/Cookie) is_admin=true - non-admin / expired / missing token → 403, admin → transparent bridge - fix LocalTime.hpp C++20 tzdb incompatibility on Apple clang (use strftime/get_time/mktime) - update example.ini and README docs for both modules
