ζ-0 Setup: Repo-Skelett, iOS-Build grün, Healthz live

- project.yml mit Bundle ev.mana.zitare + Widget + ShareExt-Targets
- ManaSwiftCore (ManaCore + ManaTokens) + ManaSwiftUI (ManaAuthUI)
  als Package-Dependencies via path:
- Pure SwiftUI für Native-Surfaces, WKWebView nur für Lese-Tabs
  (Hybrid-Sonderfall vs cards/memoro/manaspur, dokumentiert im
  Playbook ZITARE_NATIVE_GREENFIELD.md)
- Theme: paper-Variant aus @mana/themes
- ZitareAPI.healthCheck via direct URLSession (öffentlicher
  Endpoint, kein AuthenticatedTransport-Gate)
- 6/6 AppConfigTests + 1/1 UI-Smoke grün auf iPhone 16e Simulator
- Live: zitare-api.mana.how/healthz → HTTP/2 200
