Frontend Component Data Tables + Command Palette

This skill packages two related component patterns : the accessible data table and the Cmd+K command palette. Both rely on the APG Combobox pattern (the palette directly; the sortable-table header sometimes indirectly), and both must respect focus management rules. This skill builds on [[frontend-a11y-aria-patterns]] (ARIA roles), [[frontend-a11y-focus-keyboard-inert]] (focus rules and the inert attribute), and [[frontend-impl-popover-dialog-anchor]] (<dialog>showModal()).
