Modifying editable python packages will still call a rebuild using `pixi install`

Checks

• [x] I have checked that this issue has not already been reported.

• [x] I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

Changing the https://github.com/ruben-arts/pycon-de-2025/blob/e89430183c06f15d6afc8a2a2f8501a1a073cca1/src/python_bindings/src/python_bindings/person.py file in this workspace will always rebuild the package even though it should be an editable install.

gh repo clone ruben-arts/pycon-de-2025
cd pycon-de-2025
pixi i
# MODIFY THE /src/python_bindings/person.py
pixi i 
# reinstalls but shouldn't

Issue description

An editable install should never be build unless the manifest is modified or reinstall is called. The editable part works when you go into a pixi shell and run the file with python after modifing it.

Expected behavior

Leave the package alone as it's editable

I think that line is to blame: https://github.com/prefix-dev/pixi-build-backends/blob/cf6388adfff1d3abf6ab9b06f9e37238ba5e4f2a/crates/pixi-build-python/src/protocol.rs#L352-L353

I think we should return a different glob without .py files in editable mode

Possibly fixed by: https://github.com/prefix-dev/pixi-build-backends/pull/136

We should modify the globs indeed :)

This is indeed fixed by https://github.com/prefix-dev/pixi-build-backends/pull/136. I cannot reproduce this anymore.

[tdejager]

That could still benefit from a regression test though :)
