Cocos Creator 3.x Debugging: 17 Skills the Gray Screen Won't Tell You About

I've been debugging Cocos Creator 3.x for months. The gray screens, the corrupt scenes, the CLI builds that fail with cryptic errors. Each time I fixed one, I wrote a skill for my AI agent so it wouldn't happen again.

Today I'm open-sourcing all 17 of those skills.
