uv fails to install Nuitka>=4 but works for Nuitka<4 - pip can install both #18010
Description
Summary
Nuitka 4.0 has just been released, but cannot be installed with uv, while its previous versions are working fine.
See how it picks v2.8.10 as the latest available:
$ uv pip install --dry-run "Nuitka[onefile]"
Resolved 3 packages in 2ms
Would download 1 package
Would install 3 packages
+ nuitka==2.8.10
+ ordered-set==4.1.0
+ zstandard==0.25.0
But cannot find the v4.0 published on PyPi:
$ uv pip install --dry-run "Nuitka[onefile]==4.0"
× No solution found when resolving dependencies:
╰─▶ Because there is no version of nuitka[onefile]==4.0 and you require nuitka[onefile]==4.0, we can conclude that your requirements are unsatisfiable.
A workaround consist in relying on pip to install Nuitka 4.0:
$ uv pip install pip
Resolved 1 package in 1.20s
Prepared 1 package in 870ms
Installed 1 package in 9ms
+ pip==26.0
$ uv --no-progress run python -m pip install "Nuitka[onefile]==4.0"

Given that pip is capable of installing this package in the same venv, is it reasonable to expect uv pip install to also works?
