feat(web): render bash tool output as a terminal card
The bash tool already declares the `card: 'terminal'` render intent for both its call and its result, and host/connection/runtime already deliver it to the browser as callView/resultView. The Web client ignored it: rows derived from raw args, and the details panel flattened every tool's content into one soft-wrapping `<pre>`. Column-aligned output folded into a paragraph and a long listing stretched the panel without bound. `TerminalBlock` (ui-primitives) renders a command as a terminal surface: a shortened-cwd prompt line, output at `white-space: pre` in a horizontally scrolling box, a head/tail height cap with an expand control, an exit-code/signal status pill, and a copy control for the raw output. ANSI SGR runs are parsed with `anser` and resolved onto `--dsw-*` theme tokens, with literal rgb kept for values the design system has no token for. Geometry and fonts mirror CodeBlock; the clipboard write both need moved into a package-internal `clipboard.ts`. Both Web render sites for a bash call consume the intent through one derivation (`terminal-card-model.ts`), so they cannot disagree about a command, its cwd, or its exit status: the keyed BashRow carries the card resident below its summary row, and the render-site fallback row keeps it behind its existing expand control. Rows cap at 8 lines against the panel's 16. Inline output in the chat row reverses this package's stated no-inline-output convention, on the owner's explicit decision; the Agent Note records the reversal and its bound. Tests: TerminalBlock/ansi/clipboard unit specs, ui-conversation wiring specs at every render site, a built-client-graph snapshot covering both chat-row shapes, and a real-browser e2e asserting the no-wrap layout and the page's own Clipboard API.

- **依赖**:`shiki/core` + `@shikijs/langs`,经 `createHighlighterCoreSync` 搭配 `createJavaScriptRegexEngine({ forgiving: true })` 组装——不带 oniguruma WASM、没有异步初始化、对 bundle 友好。语法(grammar)白名单:`typescript`(内嵌 JS)、`shellscript`、`json`——即 harness 实际会渲染的那几种语言;其余一律回退到几何完全一致的纯文本块,绝不报错。先例:VitePress 站点已经通过 shiki 渲染全部文档代码;而在 TypeScript(正是此处要紧的载荷)上,TextMate 语法实质性优于正则高亮器。

- **单例**:`ui-primitives/src/markdown/highlight.ts` 为每个 document 创建一个 `HighlighterCore`,并公开 `highlightToHtml(code, lang)`(undefined 即渲染为纯文本)。引擎加语法的构建是一次约 120-175ms 的长任务,因此模块在插件启动时用延迟任务预热单例(惰性路径保留为正确性兜底),把这笔开销挪出渲染路径——否则流式 finalize 交换的那一刻会卡顿。别名表用 `Map` 而非对象:fence 信息串由 assistant 撰写,诸如 `constructor` 这样的标签必须落空,而不是解析到继承属性并让 shiki 崩溃。共享的 `CodeBlock` 组件同时拥有两条分支;其 shiki 分支经 `dangerouslySetInnerHTML` 注入生成的 span 树——此用法获准,因为 shiki 输出的是从代码文本计算出的静态 span 树(不流经任何用户 HTML,没有脚本或事件处理器),这正是 shiki 自身文档载明的消费路径。

- **主题化**:shiki 的 `createCssVariablesTheme` 让每一种 token 颜色都经由 `--shiki-*` 自定义属性路由;取值本身住在新增的 `ui-theme/styles/shiki.css` token 表里(亮色在 `:root`、暗色在 `body[data-ds-dark-theme]`——层叠方式与其余每张样式表相同),由壳的 `base.css` 导入链引入。组件 CSS 保持只用 token;任何字面颜色都不进入 JS 或组件样式表。背景/前景以别名指向既有的 markdown 代码块 token,使高亮块与纯文本块彼此一致。

- **表面**:markdown 围栏代码块(`MarkdownText` 的 `pre` 组件把单字符串围栏路由到 `CodeBlock`)、`run_code` 展开后的程序正文(ToolRow 的 code 变体,`lang="typescript"`),以及 details 面板的 Input 参数(`lang="json"`)。输出有意保持纯文本——工具输出是任意文本,硬猜一种语法,带来的误高亮会多于帮助。
