* feat: add Android browser preset for companion device registration
Add Browsers.android(apiLevel) preset that identifies as an Android
companion device (SMB_ANDROID platform, ANDROID_PHONE device type).
Validated against Frida captures of real WhatsApp Android protocol.
* feat: support BAILEYS_BROWSER env var for browser selection
Allows selecting Android companion mode via environment variable
without code changes. Set BAILEYS_BROWSER=android (or android:15
for a specific API level) to register as an Android device.
* fix: auto-detect Android browser in pair code and fall back to Chrome
Pair code companion registration fails with Android browser because the
WA server rejects the ANDROID_PHONE companion_platform_id over the web
Noise protocol. When Android is detected, requestPairingCode() now
transparently uses Chrome/macOS platform values for the pair code stanza
while QR code pairing continues to work as Android (SMB_ANDROID).
* docs: add android to isValidBrowserPreset JSDoc
Applied yarn lint --fix to auto-correct:
- Import spacing and sorting across multiple files
- Trailing commas
- Arrow function formatting
- Object literal formatting
- Indentation consistency
- Removed unused imports (BaileysEventType, jest from tests)
This commit addresses the linting errors reported in GitHub Actions:
- Fixed import ordering in libsignal.ts
- Fixed trailing commas in Defaults/index.ts
- Cleaned up formatting across 63 files
- Reduced line count by ~220 lines through formatting optimization
Note: Some lint errors remain (75 errors, 239 warnings) mainly:
- @typescript-eslint/no-unused-vars (variables assigned but not used)
- @typescript-eslint/no-explicit-any (type safety warnings)
These remaining issues are non-blocking and can be addressed incrementally.

Implements automatic detection of OS versions at runtime instead of
hardcoded values. This ensures the library reports accurate platform
versions to WhatsApp without manual updates.
Version Detection:
- Linux: Reads /etc/os-release for distribution version (e.g., '24.04.1')
- macOS: Converts Darwin kernel version to macOS version (e.g., Darwin 24.x → macOS 15.x)
- Windows: Uses os.release() directly (already returns correct format)
Security Fixes (from PR #62 review):
- Fix isValidBrowserPreset() to use Object.prototype.hasOwnProperty.call()
to prevent matching inherited properties like 'toString' or 'constructor'
- Fix getPlatformId() signature to accept 'unknown' type for runtime safety
Other Improvements:
- Add FALLBACK_VERSIONS constant with updated 2025 versions
- Add DARWIN_TO_MACOS mapping for accurate macOS version conversion
- Export detectedOSVersions for debugging and logging
- Improve JSDoc documentation with accurate examples
- Add 36 comprehensive unit tests (up from 25)
The version is detected once at module load and cached for consistent
behavior throughout the application lifecycle.

- Add pre-computed BROWSER_TO_PLATFORM_ID map for better performance
- Implement getPlatformName() helper with try-catch for error handling
- Add normalizeBrowserKey() for input validation (handles non-string inputs)
- Add safeRelease() wrapper with fallback for OS release detection
- Export isValidBrowserPreset() type guard for external validation
- Add comprehensive JSDoc documentation with examples
- Add 25 unit tests covering all edge cases and robustness scenarios
Improvements over original code:
- Handles undefined/null/invalid input types gracefully
- Returns default values instead of crashing on invalid input
- Platform map is alphabetically sorted and deduplicated
- Constants use 'as const' for better type inference
- Module-level caching avoids repeated proto.DeviceProps access
