- User.min_quota_pct Int @default(20) + ClaudeWorker.last_quota_pct/last_quota_check_at
- Migratie add_worker_quota_gate
- lib/schemas/user.ts: minQuotaPctSchema (int, 1-100)
- actions/settings.ts: updateMinQuotaPctAction met auth/demo/zod-guard
- MinQuotaEditor component met numeric input en DemoTooltip
- Settings-pagina: Worker-instellingen sectie
