fix(cmd/files/webui): shell 语义修复 + 根沙箱误判 + 上传注入走 interrupt + UI 区分附件来源

1. cmd_run 改经 /bin/bash -c 执行完整 shell 语法
   旧实现 shellUnquote 拆词后直接 exec：'pwd; ls /' 变成执行名为
   'pwd;' 的程序（exit -1）、heredoc 被截断、管道/命令替换全部失效——
   agent 多次反馈命令解析奇怪即此。危险命令拦截（kill homed 等）保留。

2. files 沙箱根目录判断修复
   pathWithinSandbox 在 base='/' 时 prefix 变 '//'，所有绝对路径误判
   逃逸（生产实锤：files.dir=/ 下 files_read/write/ls 全部报 outside
   sandbox）。根沙箱直接放行。

3. webui 文件上传注入改走 interrupt（system 角色）
   文件元信息不再混入用户消息气泡；用户附言作为正常消息先行注入，
   文件说明紧随其后以 no_memory interrupt 补充——对齐 terminal_watch/
   timer 工具提醒模式，聊天流保持干净。

4. 前端附件卡片按 role 区分来源
   user=右侧+『你发送的』标签+accent 底色；assistant=左侧+『小宅发送的』。
   📌 emoji 按钮换为 SVG 图标，前端 emoji 清零。

+- cmd_run 经完整 shell（bash）执行，支持管道、分号、&&、命令替换、heredoc、重定向。
+- 多步交互式程序（vim/top/ssh 会话、需要持续输入的进程）用 terminal_create 创建终端，
+  terminal_write 发送输入、terminal_read 读输出——不要用 cmd_run 硬等交互程序退出。
+- 写文件优先 files_write（原子+留档），生成多行内容时可用 heredoc 或 files_write，
+  不要用 echo 拼接长文本。
+- 读用户发来的文件用 files_read；向 webui 回传图片/文件用 output_send__webui(type=image/file)。
+
 当用户上传图片或音频时，系统会自动附着媒体内容。如果模型不支持直接处理多媒体，请使用上述工具。
