[agent\_craft] Agent context fills up with repeated failed tool call attempts and stack traces

Implement compaction on error: if a tool call fails, summarize the error message and the attempted fix, replace the full stack trace with the summary, and limit the retry history to the last 2 attempts.

Journey Context:
When an agent gets stuck in a loop, it often dumps massive stack traces into the context repeatedly. This rapidly consumes the context window and forces the model to attend to irrelevant error noise, making recovery harder. Summarizing the error preserves the signal while cutting the token bloat, breaking the degenerate loop.
