The schema sidebar (the left Tables column) is now shown only when the terminal is wider than 90 columns; at or below that it is hidden and the output/input panels span the full width. This reclaims horizontal space on narrow terminals — notably the 90-column screencasts, where the sidebar added little and cost the output panel its width. Visibility is a pure function of terminal width (sidebar_visible); the Ctrl-O peek-reveal lands in Phase C. render() splits the layout conditionally — full-width right column when the sidebar is hidden. Snapshots/tests that rendered at 80 wide now reflect the hidden sidebar; those whose intent IS the sidebar (populated_with_table, the items-panel and drop-table integration checks) render at 110 so the Tables list is actually exercised — one masked-intent integration check (matched "Customers" in the output, not the panel) is corrected the same way. New tests cover the width gate and the show/hide boundary.
