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

Implement trace-level loop detection and progress assertions. Set a hard limit on consecutive identical tool calls. For premature termination, assert that the final span contains a specific done state or artifact, rather than just checking that the agent exited without an exception.

Journey Context:
Agents often loop when they encounter an error they don't know how to fix, repeatedly trying the same failing API call. Standard timeout alerts are too coarse. By analyzing the trace for repeated sequential spans with identical inputs, you can catch infinite loops early. Similarly, agents might hit a max token limit, which registers as a successful exit code. Progress assertions ensure the run actually reached a valid terminal state.
