perf: replace debug with obug

[sxzz]

Vite side: vitejs/vite#21107
 
https://github.com/sxzz/obug is a newly developed project, forked from debug, the most popular npm library for debugging.

obug addresses several issues:

• Zero dependencies, achieved by dropping support for legacy browsers and older Node.js versions
  • Optimized for modern environments
  • Supports ES2015+ browsers
  • Compatible with Node.js 18 and above
• Pure ESM
• Extremely small footprint
  • Unpacked size: 21 KB vs 42 KB (including dependencies)
  • Production bundle size for browsers: only 3.22 kB, gzip: 1.5kB.
• Uses trusted publishing (although some consider this meaningless, this is simply to inform those who care about it; related discussions are outside the scope of this post)
