Phase 12 R0+R1: Marketplace-Restore-Plan + Schema in marketplace-pgSchema

R0 (Doku):
- Archiv unter docs/marketplace/archive/ aus managarten-Tag
  cards-decommission-base: MARKETPLACE_PLAN (654 Z., Vollvision mit
  mana-credits-Flow, Anti-Patterns), COMPETITORS, GUIDELINES,
  cards-server_CLAUDE.
- docs/playbooks/MARKETPLACE_RESTORE.md mit Schema-Naming-Entscheidung
  (eigenes marketplace-pgSchema), Wellen R0-R6, Cardecky-Skill-
  Integration, Lizenz-Modell.
- CLAUDE.md Invariante 2: Strategie-B gilt nur für Study-/FSRS-/Sync-
  Schicht; Marketplace-Restore ist explizite Ausnahme.
- STATUS.md: Phase 12 R0+R1 durch.

R1 (Schema):
- 16 Tabellen + 5 Enums im neuen marketplace-pgSchema (authors,
  decks, deck_versions, deck_cards, tag_definitions, deck_tags,
  deck_stars, deck_subscriptions, deck_forks, deck_pull_requests,
  card_discussions, deck_reports, ai_moderation_log, deck_purchases,
  author_payouts, author_follows).
- drizzle.config.ts: schemaFilter ['cards', 'marketplace'].
- Greenfield cards-pgSchema unangetastet.
- DB-CHECK decks_price_requires_license verifiziert (paid Deck mit
  CC-BY wirft sauber ab).
- type-check + 56 API-Tests grün, drizzle-kit push idempotent.

Decks dormant (kein Code-Pfad ruft die Tabellen). R2 (Backend α/β:
Author-Profile + Publish + AI-Mod) als nächstes.
