fix: increase WebSocket timeout to prevent MCP connection drops
The 5-second socket timeout was causing WebSocket connections to close
during long LLM prompt processing or slow MCP tool calls. Increased to
5 minutes to accommodate:
- Long-running MCP tools (web searches, API calls)
- LLM prompt processing that can take 10+ seconds
