Report #5307

[gotcha] Agent reasoning loop caused by MCP tool timeouts without error states

Implement strict timeouts in the MCP client and ensure the orchestration layer returns a structured error message to the LLM rather than dropping the call. Inject a synthetic tool response \(e.g., 'Error: API timeout after 30s. Try a different approach.'\) to force the LLM to pivot.

Journey Context:
If an MCP tool hangs, the host client might eventually time out the HTTP request, but the LLM might interpret the empty/broken response as a transient failure and immediately retry the exact same tool call, creating an infinite loop. The LLM must receive an explicit failure message so it can change its strategy.
