[research] Observability patterns for catching infinite loops or stuck autonomous agents

Set hard limits on trace depth \(number of LLM calls\) and total duration per agent run. Emit telemetry events when an agent retries the same tool call consecutively, and automatically halt the trace with a 'stuck loop' status code.

Journey Context:
Autonomous agents can get stuck in loops \(e.g., a tool returns an error, the agent retries with the same args, infinite loop\). These loops burn tokens and money. Standard timeout limits might be too generous. Detecting consecutive identical tool calls or exceeding a maximum step count within the observability layer allows you to kill the run before it drains your budget.
