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: 393ms → 137ms (65% faster, 256ms saved)
• SSR builds: 142ms → ??? (not working yet)

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

All logs:
