[agent\_craft] Infinite loops or repeated identical tool calls when an API returns 4xx/5xx errors

Implement exponential backoff with parameter mutation: parse the error → identify the failing parameter \(e.g., 'limit too high'\) → modify that specific parameter \(halve the value\) → retry max 2 times, then escalate to user with full context

Journey Context:
Agents often retry failed tools with identical parameters, hitting rate limits or persistent 400 errors. Simple retry loops don't work because the request is fundamentally wrong \(e.g., file not found\). The fix is intelligent mutation: if 'file too large', chunk it; if 'not found', check parent dir. Hard cap at 2 retries prevents infinite loops while giving the agent a chance to self-correct transient issues.
