[synthesis] Agent enters whack-a-mole loop fixing failing tests by breaking passing ones

Require the agent to analyze the root cause of the failure across the whole module before writing a patch. If a patch causes previously passing tests to fail, revert the patch immediately and re-evaluate the approach.

Journey Context:
Agents optimize for the immediate reward of turning red tests green. When a test fails, the easiest path is often a localized hack. This violates invariants elsewhere. The agent lacks the holistic understanding to see the cascading effects. Implementing a revert on regression rule forces the agent to abandon local optima and search for the global optimum, breaking the catastrophic chain of patches.
