chore: migrate tsup to tsdown

[Kenzo-Wada]

Migrate build tool from tsup to tsdown.

Benchmark: ~28% faster (2.87s vs 4.00s average)

Removed --env.NODE_ENV production flag as it's unnecessary - the only NODE_ENV usage is isTestMode() which should evaluate at runtime.

Thanks for the PR 🙏

The migration from tsup to tsdown looks solid and all tests are passing 👍

Given the scope of the changes, I’ll still test this version locally and may
make a few adjustments if needed before merging.

Thanks again for the contribution!

I'm all for moving this to tsdown! For reference, I am currently working on moving the qwik optimizer / compiler to oxc from swc in Rust.

I am also working on:
https://github.com/kunai-consulting/qwik-design-system

Which uses a lot of the oxc toolchain in various parts on the typescript side. All libraries are Qwik libraries with the rolldown config.

@siguici let me know if you need me to review when finished

[Kenzo-Wada]

thanks! and nice design system project :)

[siguici]

Agreed 👍

After local verification, I didn’t find any issues.
Most of the changes are formatting-related, and for the CLI package.json,
all supported runtimes now handle ESM, so this is fine for me.

I’m good to merge.

Thank you!
