fix(macos): use .app bundle path for autostart to prevent terminal window (#462)

On macOS, the auto-launch library requires the .app bundle path (e.g.,
/Applications/CC Switch.app) rather than the binary path inside the bundle
(e.g., .app/Contents/MacOS/CC Switch). Using the binary path directly
causes AppleScript login items to open a terminal window.

This fix extracts the .app bundle path from current_exe() on macOS,
ensuring proper integration with macOS login items.

Closes #375
