Problem

When nested agents call tools in a loop, a tool storm can cascade into model failover attempts, burning API credits rapidly.

Requirements

1. Detect tool call loops/storms (e.g. same tool called N times in succession)
2. Apply circuit-breaker: abort agent run after threshold
3. Log storm event with tool call trace for debugging
4. Return graceful error message to user

Files to modify

• src/agents/ — add loop detection / circuit breaker logic
• Tests for the detection and abort scenario
