[synthesis] Agent confidently repeats wrong approach for multiple consecutive steps

Implement a 'reasoning reset' mechanism that, upon detecting a repeated failed action state, strips the recent failure history from the context and forces the agent to replan from scratch with only the original goal and a high-level failure summary.

Journey Context:
When an agent fails a step, the error message is appended to the context. The agent then tries to 'fix' the error, but the failed attempt context anchors its reasoning. It generates a slightly modified version of the same failed approach. This creates a sunk-cost cascade where the context is so polluted with the specific failed implementation details that the agent cannot abstract back to an alternative strategy. Simply asking the agent to 'try a different approach' often fails because the failed code still dominates the context. The fix requires hard context amputation, not just adding more instructions.
