feat(v0210): NoteRepository revision API + NoteRevision type + InboxApi 시그니처

- updateRawText: raw_text 갱신 + user revision INSERT (atomic)
- listRevisions: edited_at DESC 순 hydrate
- restoreRevision: 옛 raw_text 를 새 user revision 으로 복원 (chain 보존)
- shared/types: NoteRevision + InboxApi 3 메서드 (updateRawText/listRevisions/restoreRevision)
- preload: 3 IPC stub 추가 (inbox:update-raw-text / inbox:list-revisions / inbox:restore-revision)
