### Actual behavior

No tailwindlsp working 

### Expected behavior

tailwindcss lsp in `phx new --install .` should work the same as `phx new --install hello && cd hello`

I meant VSCode and Zed 😅

Turns out this is not phx.new related, but rather related to devenv. My apologies.

Note: this issue goes away as soon as I remove .direnv/ and .devenv/ folders inside the repository root.

Fortunately we can instruct direnv to place its cache directories elsewhere. I'm working with the engineers at devenv to solve it there.
