Problem

SqlQueryEditor / QueryResults were never mounted in production after DatabaseManager moved to .archive. The unused feature still shipped a CodeMirror SQL stack (@codemirror/lang-sql, sql-formatter), a db_run_query shortcut, and dedicated i18n keys.

Solution

Delete the unused SqlEditor files and barrel exports. Remove the SQL-only packages, the db_run_query shortcut, and the strings that only that UI referenced (sqlEditor.*, SQL tooltips, actions.run). Keep placeholders.noQueryResults, which is still used by the shared Placeholder component.

Potential risks

If Database query UI is revived, this editor has to be restored from git history. .archive still points at the old import path and will not compile if someone un-archives it without bringing the editor back. Opening .sql files in the regular CodeMirror editor is unchanged; that path never used @codemirror/lang-sql.

Verification

• pnpm exec vitest run --config config/vitest.config.ts src/app/root/__tests__/startupGraph.test.ts src/app/root/__tests__/featureBoundaries.test.ts src/config/keyboard/shortcutBindings.test.ts src/config/keyboard/shortcutDisplay.test.ts — 4 files, 58 tests passed
• pnpm check:i18n-keys — passed (0 new unused/missing keys)
• Commit hook: lint-staged, oxlint, eslint, prettier, and staged TypeScript check passed
• NOT RUN: full pnpm test / pnpm lint / browser Database UI (feature is unmounted; no user-visible surface remains)
