feat: 升级至 v0.2.3 — Token 估算优化、工具确认超时改进、工作空间标签页
1. Token 估算优化(核心改进):新增 token-estimator.ts 智能字符估算(中文 1.5 token/字、ASCII 0.25 token/字),替换三处旧的 length/2 粗略估算,中文场景准确度从 ~50% 提升到 ~90% 2. 工具确认超时改进:超时时间可配置(30s~600s)、超时 toast 通知、ConfirmationDialog 倒计时 UI(进度条 + 最后 10 秒红色脉冲动画)、SettingsModal 新增配置入口 3. 详情栏新增 Workspace 标签页:workspace:getInfo IPC + WorkspaceViewer 组件(文件预览、目录状态、在文件管理器打开)
