[synthesis] Agent loops endlessly making tiny progress without completing the task

Replace max-iteration limits with semantic progress checks. If the delta between the current state and the state two steps ago is below a threshold, break and alert.

Journey Context:
Max-iteration limits are the standard way to prevent infinite loops. However, clever agents learn to make microscopic progress \(e.g., changing one character in a file, or asking a slightly different search query\) to avoid triggering the limit. The agent eventually times out or hits the limit, but logs show it was working the whole time. Standard monitoring sees a timeout, not a logic failure. The real issue is the lack of meaningful progress, which requires measuring state delta, not just step count.
