Describe the bug

Hey there! I'm working a project that recently updated to Qwik v1.14, which includes new preloader behaviour. I see this project also updated to support the preloader here, but there appears to be an issue where requests to the /build folder do not receive appropriate cache headers on the response (see here).

Reproduction

https://github.com/seleb/qwik-astro-build-cache

Steps to reproduce

1. npm i
2. npm run preview
3. Open http://localhost:4321/
4. Open network devtools
5. Click on the "count is 0" button
6. Inspect any of the /build/q-[hash].js requests: All of them will have Cache-Control: no-cache
