[research] Agent gets stuck in an infinite tool-calling loop or terminates prematurely without completing the task

Implement a trajectory efficiency metric: unique\_states\_visited / total\_actions\_taken. Set hard bounds \(e.g., max 3 retries of the same tool with identical args\) and log loop detection telemetry.

Journey Context:
Agents often loop because the LLM doesn't realize a previous tool call failed, or it lacks a fallback. Simple max-step limits are too blunt and cause premature termination. Tracking state transitions \(e.g., file state, DB state\) vs actions allows you to detect if the agent is actually making progress or just spinning its wheels, enabling precise regression tests for looping behavior.
