- Use synchronous pool removal in desktop disconnect_db to prevent
race condition when user quickly disconnects and reconnects
- Rename recordMetadataLoadError to recordConnectionLostError and
export it for cross-store reuse

recordConnectionLostError in queryStore catch blocks
- Add backend check_connection_health method (dbx-core) with Tauri
command and web route for proactive pool verification
- Add frontend checkConnectionHealth API (tauri.ts/http.ts/api.ts)
- Enhance ensureConnected to verify backend pool health before
assuming connection is valid, auto-reconnect if stale
- Add sort mode toggle button (folder structure / date modified)
- Sort by date: flat list with all folders and files by updatedAt desc
- Most recently modified items appear at top for quick access
- Hide 'Unfiled' label when not dragging (only show as drop target)
- Remove excessive spacing between folder tree and unfiled section
- Remove from QuickOpenDialog list items for instant keyboard navigation
- Remove from DatabaseSearchDialog results for immediate click response
- Remove from CustomContextMenu items for instant menu interaction
- Support Ctrl/Cmd+click for multi-select toggle
- Support Shift+click for additive range selection across folders and files
- Add batch delete via right-click context menu with confirmation
- Add active/inactive visual states matching connection sidebar behavior
- Remove transition-colors for instant selection feedback
- Unified selection index system for cross-type range selection
- Empty commands show temporary error hint (1s) but not added to history
- Arrow key navigation skips empty command entries
- Add appendCommandOutput helper for transient feedback
- Press ↑ to recall previous command, ↓ for next command (terminal-like behavior)
- Press ↓ at end of history to clear input
- Use readonly instead of disabled to maintain cursor focus and blink state
- Semi-transparent visual feedback during command execution
When the user triggers SQL execution via shortcut/toolbar/context-menu
without a manual selection, a floating picker now surfaces the available
execution targets:
- "Current SQL" — the statement at the cursor
- "All SQL" — the entire editor content
Each candidate is highlighted as a preview decoration in the editor as
the user navigates the picker with arrow keys. Only a single entry is
shown when the cursor statement equals the full document.
前端 SQL 范围解析器 (sqlStatementRanges.ts) 按分号拆分语句，同时跳过
字符串、引号标识符、注释和美元引用体中的分隔符，与后端 dbx-core splitter
逻辑一致。选取器支持键盘导航、鼠标悬停高亮、Enter 确认、Esc/失焦取消。
Changes:
- sqlExecutionTarget.ts: add SqlExecutionCandidate, SqlExecutionOverride types
- sqlStatementRanges.ts: frontend SQL tokeniser (new, 848 lines)
- SqlExecutionTargetPicker.vue: accessible floating listbox (new, 109 lines)
- QueryEditor.vue: preview StateEffect/StateField; requestExecute() replaces
executeCurrentSql() to route through picker
- ContentArea.vue: expose requestQueryEditorExecute() to parent
- App.vue: toolbar + global shortcut → requestActiveEditorExecute()
- i18n: editor.executionPicker keys for all locales
- tests: 26 new unit tests for sqlStatementRanges (all 1121 tests pass)
* fix(postgre): Fix the data type syntax when creating tables in PostgreSQL
* fix(ui): Save the state when closing the SQL library through the close button
