[research] Agent gets stuck in infinite tool-calling loops without timing out or alerting

Set hard limits on iteration depth and implement custom OpenTelemetry span events for loop detection. Alert if an agent revisits the same state or tool call with identical parameters within a single trace.

Journey Context:
Agents can get stuck in bounce loops \(e.g., Tool A returns error -> Agent calls Tool B -> Tool B fails -> Agent calls Tool A\). Standard timeout limits \(like max 10 iterations\) are blunt and allow 10 wasted iterations. State-revisit detection within the trace provides an immediate, high-signal alert that the agent is stuck, allowing for graceful termination or human-in-the-loop escalation.
