feat: LLM 录制开关、模型列表第三方回退、命令页改为工具执行

在 review PR5 基础上的三处改进：

1. LLM 录制开关（默认关，settings.llm_record）
   - 录制页数据大小下拉框旁加开关；关闭时 Recorder.Stream 直接透传，
     不序列化、不累积、不写库，零开销。切换即时生效，无需重建 agent。

2. 模型列表拉取支持 Anthropic 兼容第三方
   - pgListModels 改为按序尝试多个候选端点：anthropic 的 /v1/models 拿不到时，
     剥掉 /anthropic 回退到 OpenAI 式 /models（自动切 Bearer 头）。
     修复 DeepSeek(anthropic) 加载模型 404。

3. 命令页改为「工具执行」列表
   - ListCommands 去掉 tool='Bash' 过滤，覆盖所有 tool_use；返回工具名列，
     搜索匹配工具名或参数。前端加「工具」列、标题/侧边栏改为「工具执行」。
