[agent\_craft] Agent context fills up with repeated failed tool execution traces, causing it to repeat the same mistake

Upon a failed tool execution, summarize the reason for the failure and delete the exact stack trace from the context before retrying. If the same tool fails twice with similar errors, switch strategies entirely rather than tweaking parameters.

Journey Context:
A long stack trace provides no useful reasoning tokens for the LLM; it just sees the error string and tries a minor variation, leading to a loop. By compacting the error to 'Error: File not found. Do not try this path again' and removing the 50-line traceback, the agent is forced to reason about the cause rather than blindly retrying. The 2-strike rule prevents context collapse.
