优化: AI Chat 体验全面升级(图标/审批/目标提取/窗口管理)

- AI 入口图标:灯泡→星花 sparkles+发光,与灵感入口区分
- 目标提取根本性改造:用户消息规则→工具调用推理(infer_goal_from_tool_calls)
  - Vec<String>→Vec<GoalEntry>(text+status),active→completed 状态流转
  - 多条/轮提取,system_prompt 仅注入 active 目标
  - 代码拆分到 helpers.rs(解决 brace 嵌套致 pub(crate) 不可见)
- 审批修复:patch_file 全档位自动放行,批量审批防抖,乐观更新竞态保护
- 审批通知浮层:全局右上角 ApprovalOverlay,窗口遮挡时可见
- 设置导入导出移除:价值低占用空间,跨设备同步建议复制 SQLite
- 分离窗口默认置顶+置顶状态持久化(刷新后保持)
- header 菜单聚合:清空/压缩上下文收入 ... popout
- LLM 文字重叠防御:delta 重复检测+丢弃
- 置顶图标:星→大头针 pushpin
- 文档/注释更新:过期 Vec<String>/chat.rs 提取描述修正

+       设计目的:当 aichat 面板被遮挡/隐藏/最小化,有 pending 审批时,
+       用户能立刻看到通知并一键激活 AI 面板处理。
+       实现:
+       - 监听 store.state.pendingApprovals(由 AiApprovalRequired 事件驱动)
+       - 位置 position:fixed top:16px right:16px,z-index 高于面板
+       - 窗口本身 alwaysOnTop 时浮层自然置顶到所有桌面窗口上面
+       - 点击浮层 → emit 'activate'(App.vue 决定激活主面板/分离窗口)
+       - 用户关闭后 60s 内同会话不再弹(防审批流期间反复打扰),新审批追加会再显 -->
