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）
