Notes files now export to notes/ + notes.json alongside conversations.json, matching folders.json's manifest pattern: matched by conversation ID, never overwrites notes a machine already has locally, same empty-state orphan- cleanup safety guard as the existing conversation/folder sync code. Also adds Cmd+D to the "Discard" button on the crash-recovery restore prompt. Fixes two Swift 6 actor-isolation build warnings surfaced along the way: ConversationNotesService and the String filename-sanitizing extension are pure, state-free helpers called from nonisolated contexts (DatabaseService, GitSyncService) but defaulted to @MainActor — marked nonisolated.
