[research] Agent silently degrades into tool-call loops without raising exceptions

Track consecutive identical or semantically equivalent tool calls in the trace. Alert or fail the eval if the retry count exceeds a threshold without state mutation.

Journey Context:
Agents often fail to recover from an API error or bad state, repeatedly calling the same tool with the same arguments. Standard success metrics \(task completion\) just mark this as a failure, but observability needs to catch \*why\*. Counting retries without state change is a high-signal indicator of a logic trap, distinguishing it from legitimate polling.
