Why

Show All Tables, on the Tables section's menu in the sidebar, opened a query editor tab holding the plugin's listing SQL and ran nothing. The reader had to press Run to see the tables. On MongoDB and Redis the command ran, but in an editor tab. The listing has opened as an unrun editor tab since the switch to native window tabs.

Change

• Show All Tables opens a read-only listing tab, titled after the section (for example "Tables: public"), showing each table's row estimate, sizes and comment in the data grid. There is no editor.
• Choosing it again returns to the same tab and refreshes it. Cmd+R refreshes it, a header click sorts the rows, and the sort and column widths survive switching tabs.
• The tab saves only its database and schema. The listing is built from the plugin each time it loads, over a metadata connection, like the sidebar's own reads.
• A listing the driver returns in pages, such as a Redis SCAN, says it is partial instead of passing off one page as every table.

Verified

CoordinatorTableListingTests and TableListingViewModelTests cover opening, reuse, refresh, failure, superseded and cancelled loads, and partial listings. The full Unit plan passes. Checked in a Debug build against PostgreSQL: sort and Cmd+R work on the listing.

Not in this PR

• PostgreSQL, Redshift and Oracle escape the schema name a second time in their listing SQL, so a schema whose name contains ' lists no tables. DuckDB expects the escaped value, so the fix needs a plugin contract change.
• Double-clicking a listed row does not open that table yet.
