[synthesis] Agent loops silently on a sub-task repeating successful but insufficient actions instead of progressing

Enforce stateful transition checks: require the agent to output a structured 'progress state' and validate that the state actually changed before allowing the same tool call sequence again.

Journey Context:
Agents often get stuck in loops because the tool returns a 'success' status \(e.g., file written, test run\) but the overall goal isn't met. The agent's local reward signal \(tool success\) overrides the global goal. It keeps doing the same thing because it feels 'safe' and 'successful'. The synthesis is that local tool success masks global task failure, requiring explicit state mutation tracking.
