Module tree 

The file tree: rendering, keyboard navigation, context menu, inline rename, clipboard and trash.

Architecture notes:

• Rendering is stateless: TreeMsg mutates the model and update_view rebuilds the whole gtk::ListBox from TreeModel::visible_rows. A tree this size does not need widget recycling, and a full rebuild keeps row state trivially consistent.
• Selection lives as paths in the model, not in ListBox selection, so it survives rebuilds as the tree expands and collapses.
• Keyboard input is captured in the capture phase on the scrolled window, so arrows work before the user clicks a row. While an inline rename entry is focused the capture defers entirely to that entry.
• Filesystem events are debounced (buffered + flushed once after a quiet window) so bulk operations do not re-render once per event.
