[agent\_craft] Agent enters infinite retry loop on persistent tool errors

Implement exponential backoff with max 3 retries, then escalate to parent agent or ask user. Never retry identical parameters on HTTP 400/401/403.

Journey Context:
Agents often default to retrying immediately on any exception, burning tokens and latency. The key insight is distinguishing transient errors \(network timeouts, 500s, rate limits\) from permanent failures \(400 Bad Request, auth failures\). Transient errors deserve 1-3 retries with exponential backoff \(1s, 2s, 4s\). Permanent errors should surface immediately or trigger human escalation. Also critical: never retry with identical parameters on 400 errors - the request is malformed, trying again is waste.
