* fix(ai): add quick proposal confirmation buttons (all locales)
When the assistant proposes an action, render Yes/No buttons below the
message so the user does not need to type a short reply — fixing the
issue where short replies caused the LLM to re-ask instead of executing.
- aiProposalDetect.ts: pure detectors for proposal sentences/short replies
- AiAssistant.vue: inline Yes/No buttons on last assistant proposal message
- ai.ts: system-prompt rule to skip re-confirmation on short affirmatives
- i18n: 3 keys added to all 7 locales (en/zh-CN/zh-TW/ja/es/it/pt-BR)
Tests: 55/55. TypeCheck: passed.
* fix(ai): add i18n keys and UI changes for proposal confirmation
- 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
- Sync query execution errors back to connection state via
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
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
