Smart biometric auth with grace period. Skips prompt if phone was recently unlocked.

0.0.2

• Fix: Updated authenticate() call for local_auth 3.x API — AuthenticationOptions replaced with flat parameters (biometricOnly, persistAcrossBackgrounding).
• allowDeviceCredential: false now correctly maps to biometricOnly: true in the prompt.
• Added pub.dev topic tags: authentication, biometrics, security, local-auth.
• Raised minimum Dart SDK constraint to >=3.9.0 to align with flutter_lints ^6.0.0.
• Upgraded flutter_lints to ^6.0.0 — zero lint issues.
• Fix: LocalAuthException codes now map to correct AuthStatus instead of always returning AuthStatus.error.
  • noCredentialsSet, noBiometricsEnrolled, noBiometricHardware → AuthStatus.notAvailable.
  • userCanceled, timeout, systemCanceled, userRequestedFallback → AuthStatus.failed.
  • All other codes (lockout, device error, etc.) remain AuthStatus.error.
