[INTER-970] Add support for new arch

[TheUnderScorer]

Migrate native modules to the New Architecture (New Architecture only)

Migrates the Android & iOS native modules from the legacy bridge to TurboModules and drops
Old Architecture support entirely. The SDK now targets the New Architecture only.

Warning

Breaking change. The SDK now requires React Native >= 0.79 (Expo SDK >= 53) to ensure compatibility with upcoming support for API v4. The New Architecture is required. Consumers on the Old Architecture or RN < 0.79 must upgrade. Released as a major version bump.

JS / TypeScript

• Add Codegen TurboModule spec src/specs/NativeRNFingerprintjsPro.ts and codegenConfig in
  package.json.
• Access the module via TurboModuleRegistry.getEnforcing, replacing the hand-written
  react-native.d.ts augmentation.
• Change getVisitorData's native return from a tuple to an object
  ({ requestId, confidenceScore, visitorDataJson, sealedResult }), since Codegen can't express
  tuples. Internal only; the public VisitorData type is unchanged.

Android

• Module extends the Codegen-generated NativeRNFingerprintjsProSpec directly
• Single RNFingerprintjsProPackage using BaseReactPackage + ReactModuleInfoProvider (TurboModule
  registration).
• build.gradle unconditionally applies the React Gradle plugin (runs library Codegen) and always
  adds the generated Codegen source dir.

iOS

• RNFingerprintjsPro.m → .mm, with the TurboModule glue (spec conformance + getTurboModule:
  backed by the generated JSI) always compiled.
  RCT_EXTERN_MODULE / RCT_EXTERN_METHOD are kept (module registration / method export).
• Align the Swift @objc selectors/params to the generated spec.
• podspec: add install_modules_dependencies(s); exclude ios/build/** from source_files.

Native method signature cleanup

Internal ergonomics of the RNFingerprintjsPro module. No public API change.

• configure: reorder so required params come first and the only genuinely-optional ones
  (region, endpointUrl) come last. The rest always carry SDK-side defaults, so they stay required.
• Remove getVisitorIdWithTimeout / getVisitorDataWithTimeout; getVisitorId / getVisitorData
  now take a trailing nullable timeout: Double | null (null = no timeout, 0 still valid). With
  Old Architecture gone, the timeout is a genuine nullable — Codegen maps Double | null to Android
  @Nullable Double / iOS NSNumber * — so the previous negative-value sentinel is dropped.

Tooling, CI & docs

• e2e-app: prune the RN version-compat scaffolding to the 0.79 floor. Remove the 0.73–0.77
  entries from compatibility.mjs and reactNativeMetadata.ts, delete app-config-tools/arch.ts,
  expoConfigPatchers.ts, and plugins/withAndroidMavenRepo.js (the Expo 50 Maven-repo workaround),
  and drop setCompileSdkVersion / stripAndroidExtraBuildProperties. app.config.ts now hardcodes
  newArchEnabled = true.
• CI (.github/workflows/e2e-tests.yml): reduce the matrix to
  `['local', '0.79', '0.81', '0.83', '0.85'].
• Docs: README.md / sdk/README.md state RN 0.79+ (New Architecture only) / Expo 53+.
• Add a major Changeset.

Validation

• SDK: pnpm build + pnpm test (72 passed) + pnpm lint + pnpm test:dts are green.
• iOS/Android: app builds, installs, and launches on the New Architecture (via the e2e matrix).
• E2E tests green.

Pull request overview

This PR migrates the library’s native modules to React Native’s New Architecture (TurboModules + Codegen) while keeping legacy-bridge compatibility, and adjusts JS/native contracts, packaging, and CI/E2E validation accordingly.

Changes:

• Introduces a Codegen TurboModule spec and switches JS access to TurboModuleRegistry.getEnforcing, updating native return shapes (tuple → object) and aligning iOS/Android native signatures.
• Splits Android sources into old-arch vs new-arch source sets and conditionally wires Codegen sources when newArchEnabled is set by the consuming app.
• Updates tests and E2E/CI tooling (arch info UI, retry wrapper for Detox commands).

e2e-app/scripts/retry-cmd.mjs:28

• The error message says node retry.js ..., which doesn’t match this script’s name. This makes CLI guidance confusing when the command is invoked incorrectly.

if (!command) {
  console.error('Usage: node retry.js --retries=<n> "<CMD>"')
  process.exit(1)
}

Major Changes

• Dropped React Native Old Architecture support. The native module is now a TurboModule (New Architecture only) exposed via a Codegen spec.

  This is a breaking change: the SDK now requires React Native >= 0.79 (Expo SDK >= 53) with the New Architecture enabled. (e83c165)
