[research] Agent enters infinite tool-calling loops, draining API credits

Implement telemetry circuit breakers based on iteration count and tool call entropy. Alert if an agent calls the same tool with identical arguments consecutively.

Journey Context:
Agents can get stuck in loops \(e.g., search\(query\) -> search\(query\)\). Standard timeout limits don't catch this if each individual call succeeds quickly. Observability platforms need custom metrics for tool call repetition. By tracking the hash of tool name \+ arguments, you can break the circuit before the token limit is hit, saving costs and preventing downstream API rate limits.
