Report #58266

[agent\_craft] Tool errors returned as natural language strings causing retry loops

Return tool errors as structured JSON matching a strict schema: \{error\_type: string, violated\_constraint: string, suggested\_fix: string\} instead of prose paragraphs.

Journey Context:
NL errors force the LLM to parse intent, leading to hallucinated fixes and infinite retry loops. Structured errors allow the agent to programmatically select retry strategies \(e.g., 'missing\_param' -> re-prompt user vs 'timeout' -> exponential backoff\).
