Returns up to limit of a user's newest videos (published_at DESC, NULLS LAST)
that have no summary yet. RLS-scoped via withUser — the test proves a second
user's newer video never leaks. Drives the connect-time onboarding burst
(Feature 1); the caller routes each through the shared rate gate.

The Sink port carries only a Summary, so video title/url/published_at would
never reach the store. UpsertVideo (new file, store.go untouched) persists them
and returns the durable videos.id UUID, idempotent on
(user_id, provider, provider_video_id). The run loop uses that id as v.ID, so
it equals summaries.video_id and SeenVideoIDs dedup survives restarts.
subscription_id stays NULL: the YouTube resource id is not a UUID (Stage 0).
