docs(website): record native zh-CN review for the Cloud Nodes launch page

The Cloud Nodes launch page Simplified Chinese copy has no recorded native-language review. This tracks the missing human review; it does not assert that the translation is wrong.

## Problem / Goal

The merged source is [FE PR #16748](https://github.com/Comfy-Org/ComfyUI_frontend/pull/16748). Its [review request](https://github.com/Comfy-Org/ComfyUI_frontend/pull/16748#discussion_r3942284724) explicitly asked for native review of the `zh-CN` wording, and the author [recorded the limitation](https://github.com/Comfy-Org/ComfyUI_frontend/pull/16748#issuecomment-5522879266): the copy was machine-written and had not received native review.

The final-head human approvals do not attest to native Chinese fluency or a linguistic review. Reviewer identity is not evidence of either. Follow-up [FE PR #17094](https://github.com/Comfy-Org/ComfyUI_frontend/pull/17094) addressed pluralization, and [FE PR #17097](https://github.com/Comfy-Org/ComfyUI_frontend/pull/17097) removed change-detector tests. Neither records native review.

The goal is an explicit native Simplified Chinese review receipt for the shipped Cloud Nodes launch copy.

## Proposed Solution

Have a native Simplified Chinese reviewer inspect the visible copy on `/zh-CN/cloud-nodes`, including the `cloudNodesLaunch.*` strings and model-card labels introduced by the source PR. Link any needed correction PR from this issue. Do not infer fluency from a person name, profile, or generic approval.

## Acceptance Criteria

- Record an explicit receipt that native Simplified Chinese review was completed.
- Link any correction PRs, or state that no corrections were needed.
- Keep the distinction clear: absent review evidence is not proof that the translation is wrong.

Open /zh-CN/cloud-nodes and inspect the visible Cloud Nodes launch copy, including the cloudNodesLaunch.* strings and model-card labels introduced by FE PR #16748. Have a native Simplified Chinese reviewer assess the wording, then record the review receipt and link any correction PRs, or state that no corrections were needed.
