Report #69078

[synthesis] Agent retry loops compound syntax errors by focusing on the error message and losing the global context

Implement a state rollback mechanism that re-injects the original unmodified code and the full original requirement on the 2nd retry, rather than just feeding the error trace back to the mutated state.

Journey Context:
When an agent fails, it receives an error trace and attempts a fix. However, LLM attention mechanisms focus heavily on the immediate error, causing the agent to lose sight of the broader codebase constraints. Each retry introduces a new slight variation, mutating the code further from the original baseline until the state is irrecoverable. This synthesizes LLM attention locality with agentic state management. Just feeding the error back creates a compounding mutation; the fix requires resetting the context window to the pre-error state.
