Improve：优化 SQL 语义诊断范围

[zipg]

变更说明

• SQL 语义诊断只分析当前可见区域对应的完整可执行语句，避免大 SQL 编辑器反复全文解析
• 滚动停止后刷新当前可见语句诊断，并保留其它区域已有诊断结果
• 诊断片段返回的位置会映射回完整编辑器文档

验证

• ./node_modules/.bin/vitest run packages/app-tests/sqlSemanticDiagnostics.test.ts apps/desktop/src/lib/tests/sqlStatementRanges.spec.ts
• ./node_modules/.bin/vue-tsc --noEmit --project apps/desktop/tsconfig.json
• ./node_modules/.bin/oxlint apps/desktop/src/components/editor/QueryEditor.vue apps/desktop/src/lib/sqlSemanticDiagnostics.ts packages/app-tests/sqlSemanticDiagnostics.test.ts && ./node_modules/.bin/oxfmt --check apps/desktop/src/components/editor/QueryEditor.vue apps/desktop/src/lib/sqlSemanticDiagnostics.ts packages/app-tests/sqlSemanticDiagnostics.test.ts
