Consider using `pkg.pr.new` for easier testing of development builds

[SuperchupuDev]

this would allow anyone to npm i https://pkg.pr.new/fdir@<commit> to test any commit, which can be useful for testing without needing to clone the repo and link it

should be straightforward to enable, here's tinyglobby's workflow file for it: https://github.com/SuperchupuDev/tinyglobby/blob/main/.github/workflows/preview.yml
