Gives each conversation an opt-in, persistent memory file the model reads automatically every turn and writes to on its own initiative via a fenced ```update-notes``` block in its reply — no per-write approval, matching the Confab-as-CLAUDE.md-for-itself concept Rune wanted. /notes on|off|show, files live in ~/Library/Application Support/oAI/notes/, embedded ID header for future Git Sync compatibility. Adds DB migration v12.
