chore: upgrade React Native to 0.85

[descorp]

Description

Upgrades the SDK's development target from React Native 0.78.3 to 0.85.0.

This is a minimal, conservative upgrade — only version bumps and TypeScript breaking-change fixes are applied. No structural/build changes (no esm: true, no new exports field, no Metro config restructuring).

Ticket: COSDK-1293

Changes

Dependency bumps

• react-native 0.78.3 → 0.85.0
• react 19.0.0 → 19.2.3
• typescript ^5.2.2 → ^6.0.3
• react-native-builder-bob ^0.40.17 → ^0.41.0
• react-native-screens 4.11.1 → 4.25.2 (fixes ShadowNode::Shared compile error on RN 0.85)
• Android: compileSdk/targetSdk 36, Kotlin 2.1.20, Gradle 9.3.1
• iOS: Gemfile gem additions for Ruby 3.4 / Xcode 26

TypeScript fixes (RN 0.85 breaking API changes)

• NativeModule removed from RN public exports → local type in EventListenerWrapper.ts, TurboModule where appropriate
• EmitterSubscription deprecated → EventSubscription
• NativeEventEmitter.addListener callback signature → cast to (event: any) => void for RN 0.76–0.85 compatibility

Other

• peerDependencies: react-native: * → >=0.76.0 (New Architecture minimum, aligns with Expo 52)
• eslint: disabled @react-native/no-deep-imports for src/specs/ (spec files must use deep imports for babel codegen compatibility on RN 0.76–0.79)
• Added .nvmrc pinning Node 24

Consumer impact

• Minimum RN: >=0.76.0 (New Architecture required). Old Architecture is not supported.
• JDK: 17 required on Android (Gradle 9 requirement).
• No API changes — purely a toolchain upgrade.

Code Review

This pull request updates project dependencies, including React Native to version 0.85.0, TypeScript to 6.0.3, and various Android build tools. To accommodate the removal of public NativeModule exports in React Native 0.85, a local NativeModule interface is introduced, and EmitterSubscription is replaced with EventSubscription. The review feedback recommends making addListener and removeListeners optional in the local NativeModule definition to prevent compilation errors with standard modules or mocks. Additionally, it suggests replacing explicit as (event: any) => void type assertions in SessionWrapper.ts with arrow function wrappers to preserve TypeScript type safety.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
