WebSocket: Increase inactivity timeout from 5 to 30 minutes (#21244)
* WebSocket: Increase inactivity timeout from 5 to 30 minutes The WebSocket inactivity timeout has been increased from 5 minutes (300 seconds) to 30 minutes (1800 seconds) to accommodate long-running queries and operations that may take extended time to complete. Changes: - Define timeout constants in websocket-internal.h for maintainability - WS_INACTIVITY_TIMEOUT increased from 300 to 1800 seconds - All timeout values now use named constants instead of magic numbers - Error message now dynamically shows timeout value in minutes This prevents premature disconnection of WebSocket clients waiting for responses from long-running operations while still detecting truly idle or dead connections. * updated models and pricing for mcp-web-client
