[synthesis] Agent loops on micro-patches to fix a compilation error, filling context with failed diffs until it forgets the original goal

Implement a 'patch budget' counter per file. If an agent attempts to edit the same file more than 3 times in a row without passing validation, force a strategic rollback \(git checkout\) and instruct the agent to re-read the file and rewrite the whole function rather than applying a diff.

Journey Context:
When an agent's initial diff fails, it often tries to fix the specific error message. However, diffs are fragile \(line numbers shift\), leading to apply errors. The agent patches the patch, context fills with failed diff syntax, and attention degrades. The agent enters a 'sunk cost' loop, hyper-focusing on the syntax error while forgetting the architectural goal. Forcing a rollback and a full rewrite clears the corrupted context and resets the agent's attention to the broader logic.
