Contributions summary:John implemented a path watcher within the macOS app, enabling the app to monitor changes in the configuration file and reload accordingly. This involved the creation of a new `FNPathWatcher.swift` file, which utilizes `dispatch_source_t` for file system monitoring, as well as modifications to `FNConfigLoader.swift` and `AppDelegate.swift`. In addition, the user addressed whitespace issues across multiple Swift files, demonstrating attention to code style.
