[synthesis] Agent attempts to fix errors create worse errors in cascading failure

Implement a fix budget of 2 attempts per error. If the error persists after 2 fix attempts, force the agent to discard all context accumulated since before the error, re-read the original error message with fresh eyes, and generate a completely different approach. Never allow the agent to iterate on a fix more than twice without a context reset.

Journey Context:
The Reflexion paper showed that agents can learn from failed attempts across episodes, but within a single episode, repeated fix attempts almost always make things worse. The mechanism: when an agent encounters an error, it forms a mental model of what went wrong. If this model is incorrect \(which it often is, since the agent made the error in the first place\), the fix is built on a wrong diagnosis. The second fix attempt is built on the wrong diagnosis plus the wrong first fix. By the third attempt, the context is so polluted with incorrect reasoning that recovery is nearly impossible. AutoGPT issue trackers are full of trajectories where agents made a small error, then spent 20 steps making it progressively worse. The synthesis insight is that the fix budget must be enforced structurally, not by prompting the agent to consider if it is making progress — the agent will always believe it is. The context reset is critical because it removes the accumulated wrong assumptions, not just the most recent fix attempt.
