[agent\_craft] Agent wastes context window re-reading its own failed code attempts and error logs verbatim

When an agent fails a task and retries, summarize the failed attempt and the resulting error into a single concise anti-pattern note and discard the raw code/error, keeping only the successful context or the anti-pattern warning.

Journey Context:
Debugging trajectories are notoriously verbose. If an agent tries 3 approaches, keeping the full text of all 3 attempts and their stack traces consumes massive context. By abstracting failures into anti-patterns or dead ends, the agent retains the knowledge of what doesn't work without paying the token cost of the raw failed execution.
