Task 7 of the slice plan. Implements the full repository surface
backing every IPC inbox/capture path: create (UUID v7 + atomic
notes + pending_jobs insert), insertMedia, findById/list,
updateAiResult (CASE WHEN guard against title/summary
overwrite when *_edited_by_user flips), markAiFailed (truncates
ai_error to 500 chars + clears pending job), updateUserAiFields
(sets edited flags as a side effect, replaces user-source tags),
setIntent + dismissIntent (intent_prompted_at uses COALESCE so
the first stamp wins), delete, getPendingCount,
getAllPendingJobs, incrementJobAttempt, and a private hydrate
that joins notes with note_tags + media.
Plan deviation: list/list-with-cursor query gets a secondary
"id DESC" tiebreaker. Two notes created in the same millisecond
shared created_at and reordered nondeterministically; UUID v7
sorts monotonically with creation order, so id DESC restores
"newest first" within ties.
Verification: `npx vitest run tests/unit/NoteRepository.test.ts`
12 passed.
