[research] Agent loops spiral into infinite tool-calling cycles, exhausting token limits and budgets in production

Enforce hard circuit breakers on token usage and tool-call iteration depth at the trace level, and run a max iteration eval suite that specifically tests the agent's ability to gracefully abort or pivot when approaching limits.

Journey Context:
Developers test agents on happy path tasks where the agent succeeds in 3-5 steps. In production, edge cases cause the agent to get stuck in a loop \(e.g., a tool returning an error the agent keeps retrying\). Without trace-level observability on token usage and a hard ceiling on iteration count, a single runaway session can cost significant amounts. You must eval the agent's failure mode: does it recognize it is stuck and yield, or does it loop infinitely?
