v0.3.0

Minor Changes

• a6eafa4: Add OAuth provider UI to the built-in auth screens. The sign-in view now lists configured
  providers (via listOAuthProviders) as "Continue with " buttons that start the flow
  and redirect to the IdP, and a new /oauth/callback route finishes the login (reads code/state,
  calls finishOAuthLogin) and lands the user on the app. Closes the gap where the SDK exposed the
  OAuth client methods but had no UI or callback route to drive them.
