dsh-chat-widener

Widen the DeepSeek Harness Web UI conversation content area. The shipped chat
column is 748px (--dsh-chat-content-width); this plugin overrides it — default
1200px, configurable — so messages, tables and the composer all render
wider (Doubao-web-style). Pure CSS injection, no host logic, no vendor-file
patching, survives dsh upgrades.

把 DeepSeek Harness Web UI 对话内容区加宽。官方对话列宽为 748px
（--dsh-chat-content-width），本插件默认覆盖为 1200px（可配置），
消息、表格与输入框一起变宽。纯 CSS 注入：无宿主逻辑、不打补丁、升级不失效。

无残留——插件只在运行时注入一个 <style> 元素。

persistence, no other surfaces. / 本插件唯一职责就是对话内容宽度：不加按钮、
不持久化、不涉及其他界面。
