[research] Agent gets stuck in an infinite loop of tool calls draining tokens and budget

Implement observability-driven circuit breakers. Track consecutive identical tool calls or state transitions in the trace, and halt the agent run if the state fails to mutate after N attempts.

Journey Context:
LLMs often get stuck in tool loop patterns \(e.g., calling grep with the same wrong argument repeatedly\). Standard max\_iterations limits are too coarse; they allow 10 useless iterations before halting. By observing the state mutation \(or lack thereof\) in the telemetry, you can break the circuit early. This saves costs and prevents downstream systems from being hammered by redundant API calls.
