feat(skills): skill_list 可见性过滤 + skill 只读工具常驻 + 进化面板对照展示

- skill_list:默认 lead agent 改为只暴露未归档、且内置或属于当前用户的技能;
  自定义 agent 仍严格按白名单。SkillStore 不可用时降级放行全部自定义技能。
- prompt:注入系统提示词的技能列表剔除已归档(state=archived)技能。
- tools:skill_list/skill_view 只读工具改为常驻提供;skill_manage 写工具仍按
  生效配置(含 per-user 覆盖)的 skill_evolution.enabled 门控。
- curator:should_run_now 解析异常时改为不运行;get_curator_status 返回上次
  LLM 建议与实际工具调用两份记录,供前端对照。
- 前端:技能进化面板新增建议 vs 实际动作对照展示 + 配套 i18n。
