[synthesis] Model fails to recover when a tool call is interrupted or times out

Implement a client-side timeout wrapper. If a tool times out, return a specific error string: 'The tool timed out after X seconds. Please try a different approach or inform the user.' For GPT-4o, this prevents it from immediately retrying the exact same slow call. For Claude, this prevents it from assuming the tool succeeded and continuing with hallucinated data.

Journey Context:
GPT-4o's default behavior on timeout is often to retry the identical call, leading to repeated timeouts. Claude, if it doesn't receive an error message, sometimes assumes the tool succeeded \(because it issued the call\) and will attempt to parse a non-existent result, hallucinating the output. Gemini throws an internal API error. Injecting an explicit timeout error message is the only cross-model way to force the agent to pivot its strategy.
