fix(rectification): put the collect stem in the assistant bubble

The live question slot still rendered the collect prompt below the action icons when the streamed body was only a greeting. Join the GET prompt into that bubble and stop drawing a sibling collect slot.

+## BUG-488 | 口述采集题干仍画在动作图标下方，没有进气泡正文
+
+- 状态：resolved
+- 首次发现：2026-09-02
+- 最近更新：2026-09-02
+- 影响面：`rectification-agentic-chat` 最新助手气泡、`.rectification-question-slot__prompt`
+- 用户现象：开场气泡只有打招呼，采集题干仍出现在点赞/复制/重生成图标下面。staging 已是 BUG-487 的 SHA。
+- 触发条件：新 Case opening，`current_question.kind=collect_spoken`，GET 已有 prompt。
+- 根因：BUG-487 把题干接到 `assistant_message` 并允许槽位兜底。直播正文仍可能只有打招呼（replace 未进客户端 raw、或 GET 后才有 current_question），于是 `showCollectSpokenPrompt` 把同一句画在图标下。用户要的是气泡正文，不是槽。
+- 修复：不再渲染采集题槽。最新助手气泡按题干精确身份 `composeCollectSpokenAssistantText`；定稿与 snapshot 把组合文本写进该条消息状态，复制走组合文本。选择卡仍走问题槽。模型仍不自己提问，避免气泡里两句相近问法。不 bump Skill，不放宽确认门。
+- 验证：`rectification-spoken-collect` 锁气泡拼接、禁止 `rectification-question-slot__prompt`；既有 collect-prompt / v9-agent / regenerate / voice 锁保持。
+- 防复发：口述采集题干不得作为动作图标下的兄弟节点。不得用正文字符串判断「有没有问过」。不得同时让模型提问又拼接同一句服务端题干。
+- 相关记录：BUG-471、BUG-485、BUG-487
+- 复发自：BUG-487（服务端拼接后槽位兜底仍可见）
+- 修复版本：待发布
