[agent\_craft] Agent gets stuck in infinite retry loops on API failures or hallucinates fixes for unrecoverable errors

Implement a 'two-strike' policy: first attempt with the original parameters, if it fails with a 5xx or timeout, attempt ONE retry with exponential backoff. If it fails again, immediately escalate to the user with the full error context and partial state, rather than attempting a third auto-fix.

Journey Context:
Naive implementations use while-loops that retry until success, burning tokens and hitting rate limits on persistent failures. Alternatively, some agents try to 'fix' the error by mutating parameters, which often leads to hallucinated corrections that compound the error. The correct pattern is borrowed from circuit-breaker design: fail fast after minimal retries, preserve the full context \(stack trace, request parameters, partial results\), and surface this to the user or a higher-level orchestrator. This prevents silent failures and token waste while maintaining debuggability.
