refactor(web): move the produced-files row into its own plugin package

ui-conversation now owns only the conversation.chat.turnTail hole; the row,
its derivation, and its copy live in @deepseek-ai/dsh-client-ui-deliverables,
composed in or out by one cordis.yml line.

 `src/client/` is organized by domain. `contract/` is the sole inter-domain shared face (`slots.ts` slot declarations and composed props, `views.ts` shared primitives, `tool-call-model.ts`); the `skeleton/`, `chat/`, and `toolviews/` directories import contract files and never each other. `apply.ts` is the only assembly point allowed to import all three domains. The `/client` export surface is the contract only — `apply`/`inject`, the two service classes, and the `contract/` type families; implementation components and the store factory stay internal and reach the page through apply's slot registrations.
 
-A finished turn ends with the files it produced. `chat-flow.ts`'s `turnDeliverables` reads them off the mutation tools' own follow-along `locations` — a diff card, or a generic card whose `kind` is `edit` (the shape `str_replace_editor`'s insert presents) — so a turn's output is listed whether or not the closing message named it, and a new mutation tool joins by declaring what it does rather than by being added to a list. Reads, deletes, and failed calls contribute nothing; a path appears once per turn in first-seen order; accumulation resets on the turn boundary, so a turn that mutates and then ends without content text cannot spill into the next turn's row. The row renders under the closing assistant's body and above its IconActions, keyed to the same seq `assistantActionsSeqs` elects. It shows six chips (basename, full path as the title) plus an explicit remainder count, and each chip opens through the same `openFile` the tool rows use.
+A finished turn ends with a turn-tail hole: the chat view renders the `conversation.chat.turnTail` list slot between the closing assistant's body and its IconActions, once per turn at the seq `assistantActionsSeqs` elects, dispatching `TurnTailOwnerProps` (the snapshot nodes, the closing seq, and the tool rows' `openFile`). This package owns only the hole; the produced-files row that fills it — derivation from the mutation tools' `locations`, the chip cap, the copy — lives in `@deepseek-ai/dsh-client-ui-deliverables`, so composing that plugin out of cordis.yml turns the surface off while the hole renders empty at zero cost.

-完成的一轮以它产出的文件收尾。`chat-flow.ts` 的 `turnDeliverables` 从改写工具自身的跟随文件 `locations` 中读出它们——diff 卡片，或 `kind` 为 `edit` 的 generic 卡片（即 `str_replace_editor` 的 insert 所呈现的形状）——因此无论收尾消息是否点名，这一轮的产出都会被列出；新的改写工具靠声明自己做了什么加入，而不是靠被加进某张名单。read、删除与失败的调用不贡献任何条目；同一路径在一轮内按首见顺序只出现一次；累积在 turn 边界重置，因此一轮若先改写文件、随后没有正文内容就结束，不会溢进下一轮的行里。该行渲染在收尾 assistant 正文之下、其 IconActions 之上，键控到 `assistantActionsSeqs` 选出的同一个 seq。它展示六枚 chip（文本为文件名，完整路径作为 title），外加一个显式的剩余计数，每枚 chip 都经由工具行所用的同一个 `openFile` 打开。
+完成的一轮以一个 turn-tail 空位收尾：chat 视图在收尾 assistant 正文与其 IconActions 之间渲染 `conversation.chat.turnTail` list slot，每轮一次、位于 `assistantActionsSeqs` 选出的 seq，派发 `TurnTailOwnerProps`（快照节点、收尾 seq，以及工具行的 `openFile`）。本包只拥有空位；填充它的产物行——从改写工具 `locations` 的派生、chip 上限、文案——都在 `@deepseek-ai/dsh-client-ui-deliverables` 里，因此把那个插件从 cordis.yml 中组合掉即可关闭该交互面，空位以零成本渲染为空。
