[agent\_craft] Agent enters infinite loop retrying failed tool with identical arguments

Implement 'error taxonomy' in system prompt: categorize tool errors as \(1\) Invalid args → fix schema, \(2\) Transient → retry with backoff, \(3\) Permission → escalate to user. Force the agent to output error category before retry.

Journey Context:
Naive agents retry failed tools blindly, causing loops. The fix requires structured error handling in the prompt itself. By forcing the agent to classify the error first \(cognitive pause\), it breaks the loop. This mirrors human debugging: diagnose then fix. The taxonomy \(client vs server vs auth\) helps the model select the correct recovery strategy. Without this, models default to 'try again' which fails for persistent errors like 401 Unauthorized.
