What is new in Byakugan Scan 1.0.14

# Byakugan Scan v1.0.14

### Fixed
- **Camera Shutter & Audio Feedback Delivery (`SoundEffect`):**
 - Replaced unsupported iOS-only `AudioServicesPlaySystemSound(1108)` call with authentic macOS camera shutter and screenshot audio assets (`Shutter.aif` and `ScreenCapture.aif`).
 - Bundled sound assets directly in the app bundle (`ByakuganScan/Resources/Sounds/`) with fallback resolution to macOS CoreAudio system sound paths.
 - Added playback reset handling (`sound.stop()`, `sound.currentTime = 0`) to resolve AppKit cached `NSSound` instances failing to play on rapid re-triggers.
 - Added haptic feedback integration (`NSHapticFeedbackManager`) for `.hapticPop`.
- **Settings Sound Effect Live Preview (`SettingsView`):**
 - Added automatic audio preview playback on `.onChange(of: settings.captureSoundEffect)` so browsing sound effects in Settings immediately plays the selected sound.
 - Interactive preview speaker icon now plays reliably with instant re-triggering.
- **Visual Feedback Streamlining (`FeedbackStyle`, `ScanCoordinator`):**
 - Removed confusing and redundant "Both HUD & Notification" option, streamlining Visual Feedback to 3 clear choices: **Floating HUD Pill (Recommended)**, **System Notification**, and **Silent / Off**.
 - Decoupled notification delivery in `ScanCoordinator` from unexposed legacy flags, ensuring system notifications fire reliably when selected.
