[synthesis] Agent loops into increasingly convoluted code fixes instead of resetting approach

Implement a context reset on N consecutive failures: if an agent fails the same sub-task 3 times, automatically clear the conversation history of the failed attempts, summarize only the high-level goal and the fact that previous approaches failed, and prompt the agent to start from a blank slate.

Journey Context:
Simply increasing the context window makes this worse, because more failed history accumulates. Adding think harder prompts just generates more text about the failed approaches. The counter-intuitive fix is aggressive context amputation. By removing the failed code from the context, the LLM's attention is forced back to the problem space rather than the solution space of the failed attempts.
