feat: Add collectSafe helper for fault-tolerant data collection

Add a collectSafe() helper function that wraps inline collection methods
with try-catch error handling. This ensures partial device data is still
collected even if individual subsystems fail (e.g., WindowManager or
PackageManager throws).

Changes:
- Add collectSafe<T>(fallback, block) inline function
- Define fallback constants for BuildInfo, DisplayInfo, HardwareInfo,
  InstallationInfo, and LocaleInfo
- Wrap all inline collection calls in collect() with collectSafe
- Add enableLogging constructor parameter for optional failure logging
