 fix(expo): Make publishableKey prop required and remove env var fallbacks
-
-Made `publishableKey` a required prop in `ClerkProvider` since environment variables inside node_modules are not inlined during production builds. This was causing apps to work in development but crash in production TestFlight/Google Play builds because the env var would be unset.
-
-**Migration:** Pass the publishable key explicitly to ClerkProvider:
-
-```tsx
-// Before (no longer works in production)
-<ClerkProvider>
-
-// After
-const publishableKey = process.env.EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY!;
-<ClerkProvider publishableKey={publishableKey}>
-```
