/*:*
* ggaze — directory navigator
*
* Navigator is a GObject (no GtkWidget) that owns the current directory
* listing: it filters to image MIME types, sorts (name/time/size), keeps a
* cursor and a path-based mark set, watches the directory with GFileMonitor
* (debounced) and emits "changed" on structural changes so the views stay in
* sync. If the current file disappears (external delete, or trash/move) it
* falls back to the nearest. Owns no GTK state; unit-testable without a
* display. See docs/architecture.md "Responsibilities / navigator".
