firebase_auth_watchos 0.0.1-beta.1

watchOS implementation of firebase_auth, bridging the Firebase Apple SDK (FirebaseAuth) over dart:ffi for email, anonymous, and token sign-in.

0.0.1-beta.1

• Initial watchOS implementation of firebase_auth: a dart:ffi bridge over the Firebase Apple SDK (FirebaseAuth) implementing the sign-in flows a watch can run (anonymous, email/password, email link, custom token), the current-user snapshot and authStateChanges/idTokenChanges/userChanges streams, user management (ID tokens, profile updates, verification emails, password updates, delete), and password-reset / action-code handling.
• Provider/OAuth sign-in, phone auth, and multi-factor flows are not supported — they need UI the watch cannot present.
• Scaffolded with flutter-watchos plugin port, then hand-finished.
• Links the Firebase Apple SDK via the CLI's external-SwiftPM-dependency support. Verified on the watch simulator: host unit tests (13/13) and an on-simulator smoke test against the real Firebase Auth backend. Not yet verified on physical watch hardware; published as a pre-release.
