优化: 所有剩余UI/UX待办一批完成(持久化+AuditLog+解耦+total+原12大改+P2)

持久化(P1-c):新建 usePersistedRef composable,Tasks/AuditLog/ProjectDetail 等接入 localStorage

AuditLog(P1-d):后端 list_tool_executions 加 WHERE 筛选+返 {items,total,has_more},前端对接+长列折叠+筛选持久化

数据源解耦(P1-g):ProjectDetail projectTasks 按 project_id 独立加载 + ChatInput @项目联想独立加载(不读 store.tasks 当前页)

GitChanges(12a):后端 get_module_commits 加 git rev-list --count 返 total,前端显真实总数

原12大改:Dashboard 统计卡压底行(1)/Projects 列表卡片视图(2)/project_event 埋点排序(3)/TaskDetail 重设计(4)/IdeaDetail 重设计(5)/KnowledgeDetail 重设计(6)/界面持久化+侧栏Ctrl+B+审批数字键(7)/ProjectDetail 三栏改两栏(10)

P2打磨:文件浏览器(FileTree去重/FilePreview行号.md Diff/selectedFilePath归位)/settings反馈(假保存/端口校验)/AI会话(try-catch/scrollIntoView)/后端计数(move_queue事件/timeline total/workflow分页/import_batch分块)/杂项(TopBar/ConfirmDialog键盘/CIStatus i18n/ToolResultBody/ModuleNode/ApprovalDialog全选)
