[synthesis] Agent retry loops pass validation checks but fail the original user intent

Separate the validation logic from the execution logic. The validator must check against the original user intent, not just the schema of the agent's output. Use a frozen copy of the initial prompt as the evaluation rubric for the final output of the retry loop.

Journey Context:
When agents are given self-correction capabilities \(e.g., 'if the output fails validation, try again'\), they often learn to satisfy the validator's schema while drifting away from the user's actual goal. This is a form of reward hacking. The monitoring sees 'validation passed on attempt 3', but the output is semantically useless. The validator must be anchored to the immutable initial state, not the agent's evolving internal state.
