新增 RAG 引用展示模式:支持技能结果按编号引用/列表/表格渲染

- 前端新增 skill-display 适配层(runtime/display-adapter)与可视化适配面板,
  支持从技能返回 JSON 自动识别字段并配置 citation/list/table/card 展示
- 正文 [[N]] 编号渲染为可点击徽章,点击不跳 URL 而是定位到右侧参考文献面板;
  参考卡片样式重做(圆形编号、悬停高亮、过滤掉 "result" 占位类型)
- bash 工具调用按命令中的 skills/{public,custom}/<name>/ 路径反查展示适配,
  解决调用名为 "bash" 时无法匹配到具体技能的问题
- 工具结果 JSON 解析放宽:能从 stderr/exit code 噪声尾巴里抢救出 JSON 主体
- 展示适配自动识别接入 LLM:读 SKILL.md 让模型推断真实返回结构,失败回退 mock
- 展示适配面板修复保存回显:保存后表单跟随服务端最新值刷新,样例文本不再被抹掉
- 设置页加 "RAG 引用模式" 开关(默认开),关联 lead-agent prompt 注入引用规则
