- Add Shift+Enter shortcut to execute query (alongside Cmd/Ctrl+Enter)
- Add ▶ preview button to schema sidebar tables: populates editor with
SELECT * FROM serving.<table> LIMIT 100 and auto-submits
- Update hint text to show "Shift+Enter to run"
- Overview tab: fall back to information_schema when _serving_meta.json
is absent instead of showing error message; row counts show "—"
- Dashboard stat cards: same fallback — query DuckDB for table count
