Novelty check: new, update or duplicate?

Check a fresh note against what you already know: new, an update, or a duplicate.

Keeps an agent team's memory clean. Compare a new note with a summary of what's already in your notes, and Jev decides whether it's genuinely new, updates something you know, or repeats it. Duplicates never reach the morning brief.
