chore: upgrade @sentry/react-native from 7.x to 8.x

[hb2708]

Summary

Upgrade @sentry/react-native from 7.11.0 to 8.x. This is a major SDK rewrite with improved performance, new APIs, and breaking changes to initialization and configuration.

Current → Target

Package	Current	Latest
@sentry/react-native	~7.11.0	8.x

Why Upgrade

• v8 includes significant performance improvements for mobile
• Better session replay support
• Improved source map handling
• New logging API (Sentry.logger.*)
• More reliable native crash capture

Migration Steps

1. Install new version:

   npx expo install @sentry/react-native@latest

2. Review Sentry.init() options — some fields have been renamed or removed in v8
3. Update the Expo config plugin — currently using @sentry/react-native/expo in app.config.js:

   ["@sentry/react-native/expo", {
     "organization": process.env.SENTRY_ORG || "nmf",
     "project": process.env.SENTRY_PROJECT || "nmf-earth",
   }]

   Verify this plugin format is still valid for v8.
4. Run clean prebuild after upgrading:

   npx expo prebuild --clean

5. Check integration APIs — reactNavigationIntegration, mobileReplayIntegration may have changed
6. Test native crash reporting — build a release build and trigger a test crash
7. Run yarn ci to verify JS-side changes

Files Likely Affected

• App.tsx — Sentry initialization
• app.config.js — Expo config plugin entry
• ios/sentry.properties / android/sentry.properties — may be regenerated by prebuild
