fix(feishu): pass proxy agent to WSClient for proxy environments (#26397)

* fix(feishu): pass proxy agent to WSClient for environments behind HTTPS proxy

The Lark SDK WSClient uses the `ws` library which does not automatically
respect https_proxy/HTTP_PROXY environment variables. This causes WebSocket
connection failures in proxy environments (e.g. WSL2 with a local proxy).

Detect proxy env vars and pass an HttpsProxyAgent to WSClient via the
existing `agent` constructor option.
