feat(node): always-on file selection with select-all checkbox

Remove the Select/Done toggle — checkboxes and action buttons are
always visible.  A select-all checkbox in the header row follows the
standard pattern: check selects all visible items, uncheck clears the
entire selection, indeterminate when partially selected.  Navigation
and file preview are unaffected (only the checkbox selects).
