New SDK components extracted from product apps: - BLBlobClient — Azure Blob Storage upload via SAS tokens (from LysnrAI BlobService) - BLKillSwitchClient — Kill switch check from platform-service (from LysnrAI KillSwitchService) - BLLicenseClient — License key activation + status (from LysnrAI LicenseService) - BLBiometricAuth — Face ID / Touch ID wrapper (from LysnrAI BiometricAuth) - BLCrashReporter — MetricKit crash reporting (from ChronoMind CrashReporter) - BLAuditLogger — Local rotating JSON audit log (from LysnrAI AuditLogger) SDK now has 13 source files. Updated README with full component table and migration status (3 apps fully migrated, 18 wrappers total).
