feat: replace with OMS React Native SDK

[tolgahan-arikan]

Summary

Replaces the existing React Native code with the OMS Client React Native SDK built as a TurboModule/native module package.

Includes:

• TypeScript public API with Bob-generated CommonJS, ESM, and type outputs
• Android Kotlin wrapper over io.github.0xsequence:oms-client-kotlin-sdk:0.1.0-alpha.1
• iOS Swift wrapper over oms-client-swift-sdk 0.1.0-alpha.1
• npm package version aligned to 0.1.0-alpha.1
• Regular SDK example app and Trails Actions example app consuming the SDK via the workspace package
• API reference, usage docs, consumer requirements, and alpha publishing docs

Validation

• yarn typecheck
• yarn lint
• yarn prepare
• yarn sdk-example build:android
• yarn sdk-example build:ios
• yarn pack --dry-run --json
• yarn npm publish --dry-run --access public --tag alpha --json

Publish Readiness

The npm package is ready to publish for compatible native React Native apps:

• oms-client-react-native-sdk@0.1.0-alpha.1 is not currently published on npm
• dry-run publish succeeds for oms-client-react-native-sdk@0.1.0-alpha.1 with dist-tag alpha
• package contents include API.md, README.md, native Android/iOS sources, podspec, JS builds, and TypeScript declarations
• supported consumers include bare React Native apps and Expo apps that use development builds, Expo prebuild/EAS Build, or the bare workflow
• Expo Go is not supported because this SDK includes custom native code

Consumer Requirements

• Android: minSdk 26, compileSdk 34 or newer, Java 17 compile options
• iOS: deployment target 15.0 or newer
• OIDC redirect auth requires app-owned URL scheme/app-link configuration
