feat: notes in studysets, synced and merged as cards are, with tags Server: three synced tables, only additions (migration 20261002191122122-notes): `note` (its studyset, a fractional position), `note_revision` (append-only, as a card's: parents, author, report, the payload {schemaVersion, title, body}) and `note_tag` (one row per assignment, never updated, as `card_tag`). Each indexes `spaceId`, and everything goes with its space, studyset, note or tag. A migration of synced tables locks app builds from before it out of syncing (ADR 0002, rule 3): cheap now, before the first release. App, `feature/note`: - `NoteContent` is a title and rich text, merged apart (ADR 0003): a title changed on one device and the body on another both survive, a body changed on two is a conflict. - `NoteRepository` creates a note at the end of its studyset, saves an edit on the revisions it started from (`saveEdit`, as the card composer now does), says when a note was last edited (its newest head's UUID v7), counts notes per studyset, and deletes a note's revisions blanked first (ADR 0002, rule 2). - Notes share the person's tags: `setTagsOfNote`, and folding tags of one name or undoing a tag's deletion covers notes too. - The delayed deletion with its Undo moves to `core/async` (`DelayedDeletions`): `StudysetDeletions` builds on it and now takes a studyset's notes too; `NoteDeletions` deletes a single note. Tests: content, merge, payload, repository, deletions, tags, the device migration guard, and sync tests against the server (four).
