[synthesis] Agent stuck in overfitting loop making micro-adjustments based on linter feedback

Limit the number of consecutive automated retries \(e.g., max 3 attempts\), and on the final attempt, instruct the agent to revert to the original code and rethink the approach holistically rather than patching.

Journey Context:
Synthesis of SWE-agent's patching strategies and Tree of Thoughts \(ToT\) exploration. Agents react to linter errors by adding patches. If the error is architectural, the agent enters a local minimum, adding type casts and try/excepts that fix the immediate error but break the system. ToT shows the value of stepping back. The tradeoff is between fast iterative patching and holistic rethinking. Capping retries and forcing a revert breaks the overfitting loop, forcing a global reconsideration rather than local patching.
