Three.js

This skill is a hub: one catalog row pointing at ten topic references.
When the task touches a topic, read that topic's file in one hop: join
its references/threejs-<topic>.md path against the skill-dir value in
this body's wrapper header and pass the absolute path to read_file.

此技能是一个中心（hub）：一行目录指向十个主题参考文件。当任务涉及某个主题时，一步读取该主题的文件：将它的 references/threejs-<topic>.md 路径与本正文包装头（wrapper header）中的 skill-dir 值拼接，并把绝对路径传给 read_file。
