fix(demo): cargar los 25 packs sema que faltaban en la composicion de demos

Cierra la CLASE del hueco que destapo el reporte del media-player
(63f20f345): los packs sema son OPT-IN por app y la lista del layout de
demos habia crecido por goteo — 25 de los 68 packs del indice no estaban, y
sus demos sonaban con defaults crudos de familia en vez de sus firmas
autoradas: chronos, clipboard, collapsible, color-field, context-menu,
drag-drop, dropdown-menu, listbox, menubar, menu-dial, month-grid,
navigation-menu, onion-menu, path-trace, proof-of-human, range-calendar,
rotate-align, switch, time-field, toggle, toggle-group, tooltip, tree-view,
tree-grid, year-grid.

Entre ellos, los packs silenciosos de D.5/D.6 (switch/toggle/toggle-group,
tooltip, menus/arboles): esas demos ahora CALLAN o suenan sutil como su
doctrina prescribe — el cambio audible es hacia lo autorado.

Bloque contiguo y comentado (sin reordenar lo existente). Verificado:
check 74 = baseline, 0 propios.
