变更摘要

该 PR（#2772）为文档资料类变更，目的是在资料中补充 CCU 硬件资源约束的描述。改动规模较小（共修改 1 个文件，新增 13 行、删除 1 行），内容围绕 CCU 硬件资源约束的使用限制进行说明，未涉及代码逻辑、接口或配置的改动。

主要改动

• 新增 CCU 硬件资源约束描述：在资料中增加关于 CCU 硬件资源约束的说明内容（新增 13 行），用于明确 CCU 硬件资源的使用限制。
• 调整既有描述：对原有相关内容进行小幅删改（删除 1 行），使约束描述更加准确或精炼。

🤖 本次改动均为数据 / 生成 / 二进制文件（如测试用例、锁文件、媒体资源），没有可审查的代码逻辑，已跳过 AI 代码审查。
