Problem

The Feishu platform adapter was monkey-patching websockets.connect globally in _run_official_feishu_ws_client. This caused issues when running multiple platforms simultaneously — specifically, DingTalk (which also uses websockets) would break because its connection logic was being overridden by Feishu's custom overrides.

Solution

Instead of patching the global websockets module, create a local module copy for the Feishu WS client:

1. Use types.ModuleType to create a local websockets module copy
2. Copy all attributes from the original module
3. Apply _connect_with_overrides only on the local copy
4. Assign the local copy to ws_client_module.websockets
5. In the finally block, restore the original module reference

Changes

• gateway/platforms/feishu.py: Modified _run_official_feishu_ws_client to use local module copy instead of global monkey-patching

Testing

• Feishu websocket connection still works as expected
• DingTalk can now run concurrently without websocket conflicts

Impact

This is a minimal, non-breaking change that enables multi-platform deployments where Feishu and DingTalk (or other websocket-using platforms) need to coexist.
