Phase 0+1: Repo-Skelett für Cards-Greenfield

Strategie B (beschlossen 2026-05-08): Cards wird als eigenständige
föderierte App neu gebaut, ohne Code-Übernahme aus mana-monorepo.

Skelett enthält:
- apps/api: Hono+Bun mit /healthz, /version, Manifest-Endpoint, leere
  pgSchema('cards'), Drizzle-Config, erstem Vitest
- apps/web: SvelteKit 2 + Svelte 5 (runes), Vite auf 3082
- packages/cards-domain: Pure-TS, CardType-Discriminated-Union,
  SubIndex-Granularität für Reviews, Future-CardType-Set vorbereitet
- infrastructure/docker-compose.yml: Postgres 16 auf 5435
- app-manifest.json: v1.0.0, Verein-owned, beta-tier
- .github/workflows/ci.yml
- docs/LESSONS_FROM_MANA_MONOREPO.md (Read-Day-Output, 15 Lehren)

Pre-Flight für Phase 2 (Auth-Föderation): DNS cardecky.mana.how,
GitHub-Repo mana-ev/cards, Cards-App-Registrierung in mana-auth,
NPM_AUTH_TOKEN für Verdaccio.

Plan: mana/docs/playbooks/CARDS_GREENFIELD.md
