[research] Agent gets stuck in an infinite loop of tool calls or self-corrections, draining API budgets

Implement a hard circuit breaker on the trace level: set a maximum threshold for consecutive identical tool calls or total token consumption per run. If exceeded, terminate the agent and flag the trace for review.

Journey Context:
Agents often loop when a tool returns an error the agent doesn't understand, so it retries with the exact same arguments. Standard retry mechanisms don't catch semantic loops. Observability must track the sequence of actions. A circuit breaker on consecutive identical actions prevents catastrophic budget overruns.
