Obscura: Native rendering is here. No Chromium required

The implementation of the Web APIs look very broken and incomplete: https://github.com/h4ckf0r0day/obscura/blob/main/crates/obsc...

This might be faster in some benchmarks, but it's not really implementing the web.

I'm more optimistic about AI browsers based on Ladybird or Servo which are actually trying to pass WPTs.
