polish(web): one intro tip naming both ways a preset is created

Copying an existing preset — or drafting one in Creator mode — replaces
the copy-minimal skeleton hint: the creator entry exists now, so the intro
names the two real paths instead of steering everyone at one source.

 The browser edits no composition text. Editing YAML in a web textarea was a weak surface (no completion, no highlighting, no diff), so a new preset is a host-side copy of an existing one — the dialog collects an id (it becomes the directory name, which is why it must be named up front and cannot change later) and an optional display name, and `{ from, id, name? }` is all that crosses the wire. Everything else — description, composition, skills — is edited in the preset's own files, and the page's other job is getting the user TO those files: the copy completes by opening the new directory, and every custom row keeps a location action. Where the host has no desktop opener (`hasDocument: false` on the roster; remote and container deployments), the same actions answer the directory as text on the row instead of offering a button that would spawn into nothing.
 
-A shipped preset opens in the read-only viewer. It is the known-good composition a copy starts from, so reading it is the point; it offers no location and no delete — its install is overwritten by upgrades and is not the user's to manage. The intro carries the guidance a create button used to imply: to start from the smallest skeleton, duplicate 极简模式 (31 lines against standard's 233).

The intro carries the guidance a create button used to imply: duplicate an existing preset and make it yours, or let the agent draft one in Creator mode.
 
 Beside copying sits the conversational entry: when the roster carries the self-referential `cordis` preset, a dashed add-card (the Models page's affordance) stages it and starts a new session — the section closes the settings panel through the shell's owner-prop `close` and the new-session chip's own applier composes the blank session the workspace flow produces. The seat keeps a late roster load from regressing the display: staged pick first, then the composition the current session already carries, then the deployment default.

 浏览器不再编辑任何组装文本。在网页文本域里编 YAML 是弱功能（无补全、无高亮、无 diff），因此新 preset 是宿主端对既有 preset 的一次复制——对话框只收集一个 id（它将成为目录名，所以必须当场取好、事后无法更改）与一个可选显示名，跨越传输层的只有 `{ from, id, name? }`。其余一切——描述、组装、skills——都在 preset 自己的文件里编辑，而本页的另一职责正是把用户送到那些文件面前：复制以打开新目录作为收尾，每张自定义卡片也保有一个位置操作。宿主没有桌面打开器时（名单上的 `hasDocument: false`；远程与容器部署），同样的操作改为把目录以文本显示在卡片上，而不是提供一个点了没反应的按钮。

 复制旁边是对话式入口：名单携带自指的 `cordis` preset 时，一张虚线添加卡（模型页的同款样式）会暂存它并开启新会话——分区经外壳的 owner-prop `close` 关闭设置面板，新会话 chip 自己的应用器负责组装工作区流程产出的空白会话。seat 会防止晚到的名单加载回退显示：暂存选择优先，其次是当前会话已携带的组装，最后才是部署默认值。
