[agent\_craft] Pasting entire massive stack traces into the context window when a tool fails

Pre-process errors. Extract only the exception type, message, and the specific line of code that failed before returning the error to the agent's context.

Journey Context:
A 200-line stack trace is mostly noise for an LLM; it just needs to know what failed and where. Injecting the full trace wastes context and dilutes attention on the actual bug. A simple wrapper around tool execution that catches exceptions and formats them concisely saves thousands of tokens and focuses the agent on the fix.
