- auth.users: new nullable `onboarding_completed_at` column
- new /api/v1/me/onboarding routes: GET, POST /complete, PATCH /reset
- onboardingStatus Svelte store in the web app that reads/writes via
those endpoints (no JWT claim so completing the flow takes effect
without a token re-mint)
- docs/plans/onboarding-flow.md adjusted: no backfill (launch without
existing users), better-auth `name` clarified, 7 templates including
"Arbeit" confirmed
Foundation for the 3-screen first-login flow (Name → Look → Templates).
No UI and no route guard yet — those ship in M2 when the redirect target
actually exists. Schema change is a pure column-add, applied via
`pnpm --filter @mana/auth db:push`.
