Upgrade React Native 0.77 → 0.83, React 18 → 19, Expo SDK 52 → 55

[transphorm]

Summary

• Phase 1 of the React Native upgrade: bump RN 0.77.0 → 0.83.9, React 18.3 → 19.2, Expo SDK 52 → 55, and @react-native-community/cli 16 → 20 across the app workspace and root resolutions.
• Enable the New Architecture on iOS (RCTNewArchEnabled=true in OpenPassport and NotificationService Info.plist) and add the React-runtimeexecutor header search paths required by RN 0.83.
• Adapt app code and Jest setup for React 19 + RN 0.83: useRef initial values, RefObject<T | null>, typed cloneElement, mock the moved specs_DEPRECATED/* native modules, switch the lucide-icons mock to react/jsx-runtime, and add a lottie-react-native mock.
• Downgrade the new react-hooks plugin rules (set-state-in-effect, preserve-manual-memoization, immutability, purity, refs) to warn while existing violations are cleaned up (tracked in SELF-2802); strip redundant Babel test-config plugins now that preset-env targets current Node.
• Loosen mobile-sdk-alpha peerDeps to accept React 19 and RN up to <0.86; SDK is unchanged otherwise. Spec (specs/topics/RN-UPGRADE-CHECKLIST.md, RN-UPGRADE-PLAN.md) updated to record the SDK 55 fallback decision (Expo SDK 56 not yet GA on 2026-05-04).

Changes

React Native app (app/)

• react, react-dom, react-native, @react-native/*, @react-native-community/cli, expo, expo-application, expo-camera, react-test-renderer, @types/react* bumped to RN 0.83 / React 19 / Expo SDK 55 lines.
• iOS: enable New Arch via Info.plist; add React-runtimeexecutor header paths and Expo project script inputs/outputs in project.pbxproj; regenerate Podfile.lock.
• tsconfig.json extends @react-native/typescript-config directly (path no longer needed).
• jest.setup.js: update mocks for specs_DEPRECATED/modules/NativeDeviceInfo and NativeStatusBarManagerIOS; add lottie-react-native mock.
• babel.config.test.cjs: drop the hand-rolled class/spread/optional-chaining/nullish-coalescing transforms — preset-env targeting current Node now handles them, and forcing them broke under hermes-parser after the upgrade (TODO: SELF-2803).
• .eslintrc.cjs: temporarily downgrade new react-hooks rules to warn (TODO: SELF-2802).
• Code: RefObject<ScrollViewType | null>, explicit useRef<number | undefined>(undefined), typed cloneElement props, and a WebViewScreen test fix tolerant of multiple console.error calls.

Root / workspace config

• Root package.json resolutions/dependencies bumped to React 19 + @react-native-community/cli-server-api@^20.
• Re-sorted package.json files (alphabetized scripts/deps).

SDK (packages/mobile-sdk-alpha)

• peerDependencies widened: react: ^18.3.1 || ^19.0.0, react-native: >=0.76.0 <0.86.0. No source changes.

Specs

• specs/topics/RN-UPGRADE-CHECKLIST.md and RN-UPGRADE-PLAN.md updated to record the Phase 1 decision: SDK 55 fallback path (SDK 56 is not GA on npm as of 2026-05-04). Pin targets filled in for RN 0.83.9.

Linear Issues

• Related: SELF-2798 (RN upgrade), SELF-2802 (re-enable react-hooks rules), SELF-2803 (replace babel test-config subset with @react-native/babel-preset).

Test Plan

• yarn lint && yarn types passes
• yarn workspace @selfxyz/mobile-app test passes
• yarn workspace @selfxyz/mobile-sdk-alpha test && yarn workspace @selfxyz/mobile-sdk-alpha types
• iOS build (Self target) succeeds with New Arch enabled; passport NFC + camera flows smoke-tested
• Android build succeeds; smoke test launch + scan
• Push notifications still deliver via NotificationService extension

Native Consolidation Checklist

• CONTRACTS.md reviewed — no unintended contract changes
• Layer 1 bridge contract tests pass (cd app && yarn jest:run / yarn workspace @selfxyz/rn-sdk-test-app test)
• Layer 3 builds pass (app iOS, RN test app iOS, RN test app Android)
• Layer 4 manual smoke test signed off (if consolidation PR)
• No new native business logic added (logic belongs in TypeScript)
