Subject: [PATCH] fix(rebreak-native): don't crash on old dev-clients missing
 ExpoLocalAuthentication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

appLock.ts is imported from the root layout, so an unguarded top-level
`import * as LocalAuthentication from 'expo-local-authentication'` crashes the
whole app at launch on a dev-client built before the dependency was added
("Cannot find native module 'ExpoLocalAuthentication'"). Load it via a guarded
require; if absent → app lock reports `available: false`, everything else runs.
Real builds (EAS / fresh prebuild) ship the module and work normally.
