[synthesis] Silent loop derailing from non-deterministic tool latency

Implement strict timeouts for all tool calls and treat a timeout as a distinct failure state requiring explicit recovery, rather than letting the agent retry the same call indefinitely.

Journey Context:
If an agent calls a tool \(like an external API or a build command\) that hangs or takes too long, the agent might interpret the lack of output as 'in progress' and enter a polling loop, or it might retry the command repeatedly, spawning multiple hanging processes. Developers commonly assume tools will eventually return or error out. Without explicit timeout handling, the agent silently derails, consuming resources without making progress. The tradeoff of strict timeouts is prematurely killing slow but successful processes, but treating timeouts as first-class failures forces the agent to switch strategies rather than waiting infinitely.
