Add knip + initial config

[webpro]

Hi there! Coming from https://bsky.app/profile/flipvh.bsky.social/post/3llc7vid6bk2j.

This enables to run pnpm knip from the root of the project. The initial results seem promising.

Unfortunately, path aliases in config files aren't supported so I rewrote two imports.

Not sure how to set environments properly? I tried to import 'dotenv/config'; but that doesn't seem to do the trick. Once we got environment variables loaded we can remove backend from ignoreWorkspaces.

thats great @webpro , thnks! I had some rough moments with getting it working with just dotenv a while back so resorted to use @dotenv-run/core: https://www.npmjs.com/package/@dotenv-run/core. I can't remember exactly what were the complications but could again have been related to the aliases and the way the frontend imports some of the backend schemas (and by extension typescript likes the env variables to be present?) .. 😵 . Maybe I should just drop the aliases in the backend... its used here:

cella/backend/src/env.ts

Line 6 in 94bdc4f

dotenv({

Yeah I'm not too familiar with the codebase goals and specifics, so I won't prescribe how to run the show with regards to environment variables.

Path aliases should generally not be an issue at all when using knip-bun over knip.

Feel free to mention me here, in other PRs, Discord, you can AMA.

Merged it #485 ! Will revisit the issue for the backend once I have some time, its already looking pretty useful for the frontend!
