Ship built assets for all apps

[ankush]

Context: https://github.com/frappe/frappe/blob/develop/.github/workflows/publish-assets-develop.yml

Right now, frappe ui apps are taking way too much time to build and because there are several of them, a bench containing 5 of them will spend ~8min just building assets. This is quite slow for first release.

We have asset caching per commit but that requires at least one more run.

Ideally:

• Ship built assets somewhere maybe a special FC service.
• Download built assets (not source! so node_modules will be empty)
• If force rebuilding then download source and reattempt

This will reduce build times and size of docker images.

All frappe-ui/React apps just need to be compiled (that takes the most time) - why not just store the final output in the repo itself (similar to how node packages are published) and avoid the build step altogether? Could this be done via a GitHub action? I'm not sure if this would work, but why not?

That will increase git repo size (with history) quite a bit IMO. Frappe and ERPNext are already 1GB+. Something like LFS is sensible though.
