Add a `preferImmediatelyAvailableCredentials` option to `signIn.authenticateWithPasskey()` and `signIn.passkey()`. In Expo apps on iOS and Android, it limits passkey sign-in to passkeys already on the device. When there are none, the request fails with `passkey_registration_cancelled` and the system's "use a passkey from another device" sheet doesn't appear, so an app can prompt for a passkey automatically on sign-in. Browsers ignore it.

Map the Android no-credential result to the documented error.

When the preference is enabled and Android returns NoCredentialException, authenticateWithPasskey throws passkey_retrieval_failed instead of passkey_registration_cancelled. Callers that handle the documented code can miss the fallback.

Suggested fix 

-      error: mapNativeErrorToClerkWebAuthnErrorCode(error.code, error.message, 'get'),
+      error:
+        preferImmediatelyAvailableCredentials && error.code === 'NoCredentialException'
+          ? new ClerkWebAuthnError(error.message, { code: 'passkey_registration_cancelled' })
+          : mapNativeErrorToClerkWebAuthnErrorCode(error.code, error.message, 'get'),

Review comment at @packages/expo-passkeys/android/src/main/java/expo/modules/clerkexpopasskeys/CredentialManager.kt at line 33:
Update the error mapping in authenticateWithPasskey so that when preferImmediatelyAvailableCredentials is enabled and Android returns NoCredentialException, the error uses the documented passkey_registration_cancelled code; preserve mapNativeErrorToClerkWebAuthnErrorCode for all other errors.

Guard the iOS 16 authorization option.

AccountManager is available from iOS 15, but this call uses an option introduced in iOS 16 without #available(iOS 16.0, *). The package targets earlier iOS versions, so the unguarded call blocks compilation for its supported deployment target. Use performRequests() on earlier versions, as the module already does for another iOS 16 API. (developer.apple.com)

Review comment at @packages/expo-passkeys/ios/AccountManager.swift at line 72:
Guard the iOS 16-only option in AccountManager by checking iOS availability before using preferImmediatelyAvailableCredentials. Use performRequests() on earlier iOS versions and retain the existing option-based behavior on iOS 16 and later.

Document the native rebuild requirement.

If an Expo update sends this JavaScript to a binary with the old native module, the extra argument causes passkey sign-in to fail on Expo SDK 54, even when the option is omitted. Tell consumers to rebuild the app and use a new runtime version before publishing the update.
