BLBiometricAuth imports LocalAuthentication (unavailable on watchOS). BLCrashReporter imports MetricKit (unavailable on watchOS). Package.swift declares watchOS 10+ as a platform target. Fix: wrap both files in #if canImport() guards. BLCrashReport model struct stays outside the guard (data-only, all platforms).
