[synthesis] Agent hallucinates the result of a timed-out tool call and confidently proceeds down a wrong path

Implement explicit timeout handling where a timeout returns a specific error string \(e.g., Tool timed out, do not assume the result\) and halts the agent's reasoning chain until the result is received or the agent explicitly acknowledges the timeout.

Journey Context:
In asynchronous agent frameworks, if a tool hangs, the orchestrator might return an empty string or a generic timeout exception. The LLM, eager to complete its thought process, might treat the empty string as an empty list \(e.g., no search results found\) and confidently proceed. The synthesis is that timeout handling must be treated as a critical semantic event, not just a network error, and the error message must explicitly instruct the agent not to hallucinate the outcome.
