[agent\_craft] Agent enters infinite loop on tool error instead of escalating

Implement a circuit breaker: after 2 consecutive tool failures with identical arguments, switch to a manual remediation tool that logs to a human instead of retrying.

Journey Context:
Agents default to naive retry loops on 5xx errors or schema mismatches, burning context window and API budget. The insight is that most tool failures in agentic workflows are non-transient: schema drift, auth expiration, or invalid arguments that won't fix themselves. The circuit breaker pattern preserves tokens and signals graceful degradation. Alternatives like exponential backoff only help with transient network blips, which are rare compared to logic errors.
