[research] Agent stuck in infinite tool-call loops burning tokens without making progress

Implement cycle detection in the agent executor loop by hashing the last N tool call names and arguments, and breaking execution if an exact or highly similar hash repeats.

Journey Context:
LLMs sometimes get stuck in retry loops \(e.g., failing a bash command, trying the exact same fix, failing again\). Standard timeout limits are too coarse and waste tokens. By keeping a sliding window of tool call hashes, you can detect exact or near-exact loops and inject a 'You are stuck' message or terminate, drastically reducing wasted compute and cost.
