…rectness, and architecture improvements

Critical fixes:
- Fix Android exportKey compilation error (undefined keyPair variable)
- Fix Android importKey type mismatch (KeyPair vs KeyPairEntry)
- Fix iOS silent failure in getRandomValues (now calls fatalError on CSPRNG failure)
- Fix iOS importKey key size calculation (derive from modulus, not DER blob)
- Fix iOS ASN.1 DER parsing with proper length decoding (replaces hardcoded offsets)
- Fix iOS hardcoded exponent with parsed value from key data

Security & safety:
- Eliminate all force-unwrap (as!) casts in iOS via typed KeyEntry struct
- Add synchronized blocks to all Android keyStore accesses for thread safety
- Add key usage validation in JS verify() to match WebCrypto spec
- JS getRandomValues validates returned length matches requested length

Architecture:
- Migrate bridge serialization from number[]/[NSNumber]/ReadableArray to Base64 strings
  across all layers (iOS, Android, TypeScript spec, JS polyfill), reducing serialization
  overhead from ~400% to ~33%
- Extract iOS RSA DER parsing/construction into standalone RSAKeyUtils.swift for testability
- Replace Android hand-rolled X.509 DER construction (~60 lines) with platform RSAPublicKeySpec
- Remove dead code (getCryptoAlg), fix typos, clean up unused parameters

Infrastructure:
- Fix Jest config (testMatch pattern, setupFiles path, test import paths)
- Add unit tests for digest, getRandomValues, importKey, verify, and polyfill installation
- Update mocks to match Base64 bridge interface
- Remove private:true flag, remove nonexistent ./cpp from files array
- Update Android SDK defaults to 35
Harden native crypto bridge with security, correctness, and architecture improvements
Android module is on the wrong path.
Add biometric auth and fix the android implementation
by using android keystore.
Configures automated testing for packages/react-native-webcrypto-bridge:
- Android: JUnit/Robolectric tests via Gradle on Linux executor
- iOS: Swift Package Manager tests on macOS executor
- Both jobs run in parallel with intelligent caching

Jobs restore dependencies from cache based on build.gradle/Package.swift
checksums, reducing build times by 50-70% on subsequent runs.

Test results and artifacts are stored for CircleCI reporting.
Change xcode from 'latest' to '16.1' to match CircleCI schema requirements.
Xcode version must be a specific version string, not 'latest'.
Change macos.m1 to macos.medium for valid Xcode 16.1 compatibility.
Remove unnecessary environment variables.
Change cimg/android:latest to cimg/android:2024.12 (a valid versioned image).
CircleCI requires specific image versions, not 'latest' tags.
The circleci/macos orb doesn't provide executor definitions.
Use simple custom executors with direct Docker and macOS config.
