Subject: [PATCH] fix(swift-sdk): guard BLBiometricAuth and BLCrashReporter for
 watchOS compatibility

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).
