chore: untrack accidentally committed build/ + ignore

xcodebuild legt build/-Verzeichnis ab. .gitignore deckte nur .build/
(Swift Package Manager), nicht das Xcode-build/. Bei v1.5.0-Commit
sind ~400 Compiler-Artefakte (.o, .stringsdata, .pcm) rein-gerutscht.

Diese Files werden hier untracked und das Verzeichnis future-proof
ignoriert. Das v1.5.0-Tag verweist weiterhin auf den schmutzigen
Commit — Konsumenten ziehen mit dem nächsten pull diesen Cleanup
nach. Saubere v1.5.1 wäre Overkill für ein Artefakt-Aufräumen.

+## [1.5.0] — 2026-05-14
+
+Minor — `getProfile()` + `ProfileInfo`. Apps können den 2FA-Status
+des eingeloggten Users lesen, damit AccountView entscheidet ob
+"Aktivieren" oder "Deaktivieren" angezeigt wird.
+
+### Neu
+
+- `ProfileInfo` (public struct) — `id`, `email`, `name`,
+  `emailVerified`, `twoFactorEnabled`.
+- `AuthClient.getProfile() -> ProfileInfo` — lädt aktuelles Profil
+  vom Server (`GET /api/v1/auth/profile` → Better Auths
+  `/api/auth/get-session`). Nutzt Session-Token als Bearer.
+
+### Tests
+
+- 4 neue Tests (twoFactor-on, twoFactor-off, ohne Session,
+  unauthorized). 70/70 grün.
+
+## [1.4.0] — 2026-05-14
+
+Minor — 2FA-Enrollment (Mini-Sprint B). Setzt Mini-Sprint A
+(`v1.3.0`) voraus. Komplett additiv.
+
+### ManaCore — 2FA-Enrollment
+
+- `TotpEnrollment` (public struct) — `totpURI` (für QR-Code-Display)
+  + `backupCodes` (Liste).
+- `AuthClient.enrollTotp(password:) -> TotpEnrollment` — aktiviert
+  TOTP-2FA; Server generiert Secret + Backup-Codes.
+- `AuthClient.disableTotp(password:)` — deaktiviert wieder.
+- `AuthClient.getTotpUri(password:) -> String` — Re-Display für
+  zweites Authenticator-Gerät.
+- `AuthClient.regenerateBackupCodes(password:) -> [String]` — neue
+  Codes, alte werden ungültig.
+
+Alle vier Methoden senden Bearer-Header mit Session-Token (Wire-
+Konvention für mana-auth-Account-Endpoints).
+
+### Server-Side Voraussetzung
+
+`mana-auth` ≥ Commit der Wrapper-Endpoints:
+- `POST /api/v1/auth/two-factor/enable`
+- `POST /api/v1/auth/two-factor/disable`
+- `POST /api/v1/auth/two-factor/get-totp-uri`
+- `POST /api/v1/auth/two-factor/generate-backup-codes`
+
+### Tests
+
+- 7 neue Tests (Success-Pfade aller vier Methoden, leeres Passwort,
+  ohne Session, falsches Passwort). 66/66 grün.
+
