chore: remove deprecated @types/react-native

[y0n0zawa]

Background

Since React Native 0.71, type definitions are included in the react-native package itself, making @types/react-native unnecessary and deprecated.

Including this package in dependencies causes deprecation warnings to be displayed to users.

Changes

• Remove @types/react-native from devDependencies
• Remove @types/react-native from peerDependencies
• Remove @types/react-native configuration from peerDependenciesMeta
• Remove related unused packages from yarn.lock (358 lines)

Test Plan

• [x] Build completes successfully
• [x] Type checking passes
