cli: Reading from stdin is broken in 4.0.0-alpha.25

[bep]

mkdir tailwindtest
cd tailwindtest
npm i @tailwindcss/cli@4.0.0-alpha.25 tailwindcss@4.0.0-alpha.25 --save-dev
echo "@import 'tailwindcss';" > foo.css

This works:

npx tailwindcss  -i foo.css -o bar.css

This fails:

npx tailwindcss  --input=- -o bar.css < foo.css

Output:

~/d/tailwindbug ❯❯❯ npx tailwindcss  --input=- -o bar.css < foo.css                                                                             main ✱ ◼

Downgrading to alpha 24 and it works:

npm i @tailwindcss/cli@4.0.0-alpha.24 tailwindcss@4.0.0-alpha.24 --save-dev
npx tailwindcss  --input=- -o bar.css < foo.css

@bep Thanks for the bug report! There's an issue in the base path it uses when configured with stdin input files. Will put out a fix shorty!

@bep Merged a fix for this now, it will be part of the next patch release. Thank you again!
