[research] Agent gets stuck in infinite tool-calling loops draining API budgets without failing

Set hard limits on per-run token usage and tool call counts, and implement real-time telemetry alerts that trigger when an agent exceeds the 90th percentile of historical step counts for a given task type.

Journey Context:
Agents often loop \(e.g., repeatedly searching for a file that doesn't exist, or getting stuck in a ReAct reasoning loop\). Because each step returns a 200 OK, standard uptime monitoring doesn't catch it. You need observability on step depth and cumulative token cost. If a baseline task takes 5 steps, and an agent hits 15 steps, kill the run and alert, rather than waiting for the max context window to exhaust.
