table_column_filters

Every data table supports a global search and a per-column filter row ( ColumnFilterRow.svelte ),
matching the usability of html_export_list_views.
Text / path / body columns use searchable inputs; closed sets ( idea kind, reference type, ideaset kind, base ready )
use select / multi-select from a fixed option list.
Column filters are applied in the ui-sql layer ( webview-table-queries.ts ) together with existing chip filters.
Table panels must bind AppState query / rows via Svelte 5 `$derived` ( not legacy `$:` ) so filtered results from
the extension message listener re-render — same pattern as graphical_graph / GraphView.
Bases table filters client-side in the webview; other tables round-trip search through ideas-summary-panel.ts.
