feat(web): attach selected reply text to the next message - #856
Codex Desktop lets a selection inside a reply travel with the next message
as a response annotation. The Web client had no such entry, so browser and
phone users could not quote a reply.
The selection becomes an annotation in the composer's own input state and
joins the message text on send, exactly as Desktop composes it: the
`# Response annotations:` block with its entries and instructions, then
`## My request:` and the body. The text is byte-compared against the
installed app's prompt assembly, whose output is recorded as a fixture.
Nothing on the Host, protocol, or persistence side changes.
The selected text itself follows Desktop's own extractor, recorded the same
way from the installed app: block edges and breaks become newlines,
paragraphs keep a blank line, table cells are tab separated, and a list
contributes only its items' text. The action is drawn above the selection
and bounded by the viewport on a pointer platform, below it on a touch one.
A reply's `:codex-annotation{index="N"}` reference is read as Markdown
syntax rather than rewritten after parsing, so code spans, fenced blocks,
escapes and link text keep their own meaning, and the same node carries the
reply's reference through streaming and settled renders. Sent bubbles and
citations read the annotation back from the logged message text, so a
reloaded transcript shows the same row the send left behind.
One proposal page plus the capability spec, with one requirement for each
observable behavior: attaching a selection, the sent format, the sent row,
and reference rendering. Tasks carry the checks that actually ran, including
the client typecheck comparison and that no native Desktop comparison was
performed.

新功能
可从助手回复中选择文本并添加到聊天；所选内容和评论会显示为可查看、可移除的批注。
批注可与正文一同发送，也可单独发送；发送失败时草稿会恢复。
支持在助手回复中展示批注引用及其详情，并提供中英文界面文案。
文档
补充了选中文字添加批注及批注展示方式的说明。
Web 客户端新增回复文本批注功能。用户可将已完成回复中的选中文本加入 Composer，查看或移除批注，并随消息发送。已发送消息和助手回复中的批注引用也可解析并展示。
Reply citations of selected text will not display, because the lookup always returns an empty list. Editing a sent message that carried annotations drops them. A failed send can attach the wrong annotations to the next message, and annotated drafts sent through a command ignore their annotations. The core attach-and-send flow works, but these gaps should be fixed before merge.

The reported history symptom needs one user message whose annotation prefix and request separator land in different text blocks. The composed message is built as a single string and forwarded unchanged to the send path, and requestBody has no other path that would divide the text. No supported path inspected here produces that split, so the concern does not establish a reachable defect.

直接读取消息数据上的 responseAnnotations。
ChatNodeStore.turnDataSource 返回 ChatNodeDataMap[Kind][]，不是包含 data 的节点数组。message.ts 将 responseAnnotations 写在该消息数据的顶层。这里读取 node.data?.responseAnnotations 会始终得到空结果。
因此，即使消息气泡已显示批注，回复中的有效批注引用也无法解析，最终被渲染器隐藏。请改为读取顶层 responseAnnotations，并移除 Line 65–68 中掩盖数据形状错误的类型断言。

Summary
Codex Desktop 支持在回复中选中文字后用「Add to chat」加入下一条消息，Web 端没有这个入口，浏览器和手机用户无法引用回复内容。本 PR 补上这个入口。
<br>是换行，相邻段落之间空一行，表格单元格用制表符分隔，列表只保留条目文字、不写自造的标记或编号；固定样例与安装包内 Desktop 选区序列化的实际输出比对。桌面视口把入口画在选区上方并按自身宽度收到视口内，触摸视口画在选区下方，避免遮挡手机系统自带的选区菜单。# Response annotations:、使用说明、<response-annotations>包裹的结构化条目，然后是## My request:与用户正文。就相同的条目与正文而言，该文本与安装包内 Desktop 拼装函数的输出逐字节相等（含说明文字里的标点与正文后的结尾换行）；真实选区另按上一段的选区规则对齐。只有批注、没有正文的消息同样可以发送，发送按钮照常可用；发送失败时正文与批注按发送先后一起回到 Composer，用户已移除的批注不会被旧记录带回。:codex-annotation{index="N"}在 Markdown 语法层识别，显示为「Annotation N」并可展开对应选中文字。行内代码、代码块与转义示例保留原文；作为指令识别但序号不合规或找不到对应批注时不显示任何内容；出现在链接文字里时只保留标签文字，不在链接内嵌套交互控件。流式中与完成后渲染一致。固定的 57 组词法样例已与安装包内 Desktop 的实际输出逐条核对，覆盖代码与转义、链接、Tab、CRLF/LF/CR、单双引号及转义引号、混合属性边界、可选指令标签、连续属性片段和相邻正文；原生可选标签[...]和连续属性片段完整消费；{index="1"}{ index="2"}取批注 2，无空格的{index="1"}{index="2"}仍取批注 1，完成态与流式中均可展开对应选中文字。该比较只证明这些已执行样例。Host、协议与持久化均未改动：批注作为普通消息文本传输，这正是 Desktop 已经在写的内容。
这些差异与范围记录在 proposal 和功能文档中：
source定位字段。Desktop 用 Codex 原生 item id 与该回复渲染出的 DOM 文本偏移定位；Web 侧的 item id 由 Adapter 生成、DOM 也不同源，写近似值会与 Desktop 冲突。原生解析允许条目省略该字段，Web 消息确实不提供这个来源定位。Related issues
