Is this for the template or generated projects?

Generated Project (tooling, structure)

Feature Summary

The goal here would be to shave on CICD costs by having a lighter weight baseline cocker container that we start from based off of the great start that UV's docker container already provides. So for example it might just come with many of the CICD tools like ruff and such pre installed rather than every new user needing to maintain a separate cache of tools.

Example

Pretty much just replacing the referenced docker images in github actions / other workflows to reference custom ones.

Additional Context

This task may be helpful for progressing toward fully platform agnostic CICD. Overall its super low priority, but represents a decent area that a lot of simplification could be wrapped into if it turns out to work well for our use case.
