Rolldown experiment

[Blankeos]

It seamlessly works w/ dev. - Build for prod gets stuck though, but yeah it's quick.

Switching from Vite to Rolldown shows significant performance gains:

Speed improvements

• Client builds: 2.81s → 1.52s (46% faster, 1.29s saved)
• SSR builds: 1.98s → ??? (not working yet)

Consistently seeing a 10-20% delta in build times across runs.

All logs:
