Module file_watcher 

Filesystem watcher for auto-scanning new/changed audio files, DAW projects, presets, plugins, PDFs, and MIDI.

Uses the notify crate (FSEvents on macOS, inotify on Linux, ReadDirectoryChangesW on Windows) to watch configured scan directories. On create/modify, classifies paths by extension, maps each path to a scan root (parent dir for files; bundle dirs as-is), debounces 2s, collapses nested roots, then emits file-watcher-change with roots_by_category so the UI runs each scanner only on those subtrees.
