adopt-upx

Use this skill when the user wants to make their skills use upx — the fast local-first package runner shipped by universal-plugin. Trigger on phrases like "make my skills use upx", "adopt the upx runner", "speed up npx calls", "switch to upx", or "rewrite npx pins to upx". Rewrites npx <pkg>@<version> references to a caret range on upx (^<major>, or ^0.<minor> for a 0.x pin) across one skill, a named set, or every skill in the project.
