Overview
Plugin.Maui.BiometricPlus is a one-shot Face ID / fingerprint / device PIN prompt for MAUI. AppLock owns the lock timer, cover, and gate after background. This plugin answers AuthenticateAsync once and reports availability. Android uses AndroidX BiometricPrompt (API 23+). iOS uses LAContext; Face ID needs NSFaceIDUsageDescription. nuget.org already reserved Plugin.Maui.Biometric (FreakyAli), so the package id is Plugin.Maui.BiometricPlus while the repo stays Plugin.Maui.Biometric.
