[synthesis] Agent enters silent recursive self-correction loop with slightly varying errors

Implement semantic similarity loop detection on action/error pairs, or enforce a strict '3 strikes rollback' rule where the agent must revert state and change strategy after 3 consecutive failures.

Journey Context:
Agents often get stuck in loops: Error A -> Fix A introduces Error B -> Fix B reintroduces Error A. Because the error messages or code diffs vary slightly, standard string-matching loop detectors fail. The agent silently spins. People try to increase the LLM's temperature or context, but the root cause is state-based. The fix is semantic similarity checks on the agent's trajectory, or a hard rule that 3 failures means the current strategy is fundamentally flawed and requires a state rollback and pivot.
