-%% @doc Watches the XDG application directories for changes.
-%%
-%% Starts one `fs' (native inotify) watch per existing directory
-%% returned by `er_xdg_pipe_menu_scanner:data_dirs/0' and subscribes
-%% to its file events. On any event, a debounce timer is (re)started;
-%% once it fires with no further events in the window, the menu cache
-%% is invalidated so the next request gets a freshly rebuilt menu.
-%%
-%% `fs' watches recursively (it drives `inotifywait -r' on Linux), so
-%% changes in vendor subdirectories (e.g. `applications/kde4/*') are
-%% picked up without any extra handling here.
