feat(skills): 自我进化前端 — Skills 独立侧边栏 + /skills/evolution 页面

UI 重构：
- settings-dialog.tsx：把 Skills section 从设置弹窗移除
- workspace-nav-chat-list.tsx + WorkspaceRoutes.tsx + SkillsPage.tsx：
  Skills 提升为独立侧边栏导航项，/workspace/skills 路由直接渲染
  SkillSettingsPage（同事原型已就绪）
- skill-settings-page.tsx：顶部追加 "自我进化" 跳转按钮

自我进化页面：
- /workspace/skills/evolution 子路由 → SkillEvolutionPage 包装
- skill-evolution-panel.tsx：三段式
  · 状态卡：启用/暂停徽章 + 累计运行次数 + 上次运行时间/摘要 +
    技能计数 (total/active/stale/archived) + 立即执行按钮
  · 配置表单：enabled / curator.enabled / interval_hours /
    stale_after_days / archive_after_days / moderation_model_name
    本地暂存 → 保存调 PUT，热生效
  · 日志面板：拉 GET /api/curator/logs，2 秒自动刷新，monospace
    展示，warning 黄、error 红
- core/curator/api.ts + hooks.ts + types.ts：TanStack Query 包装
  status / config (GET/PUT) / run / logs

i18n：
- types.ts 新增 settings.skillEvolution.* 类型签名
- zh-CN.ts / en-US.ts：状态卡 / 配置表单 / 日志面板文案，
  以及 settings.skills.goToEvolution
