 *   (`debounce`) on the setter — never written on every keystroke.
 * - `sort` / `dir` follow the shared sort convention (two scalar params).
 * - `rows` filters by row-count bucket; `owner` filters by creator id. Both are
 *   multi-select arrays.
 *
 * Selecting a table navigates to the `tables/[tableId]` route (via `router`),
 * so the active table is route state, not query state, and is intentionally not
 * represented here.
