Please support (and respect) --link-mode in uv python install

[nbelakovski]

Summary

A number of uv commands support the --link-mode option, but not python install. As a result when I mount a directory with a venv inside docker for local development, it can't python python because it's symlinked to a directory that's not in the container.

It seems like it should be straightforward to add this to python install? And of course if I run uv sync --link-mode <option> then the python it chooses to install or use should respect that as well.

Does this make sense and is it a reasonable request?

To pick at the details a bit here: this isn't a python install behavior, it's virtual environment behavior. Copying the Python installation into virtual environments makes them "full" environments — not virtual. We'd need a larger concept than link-mode to represent this since we wouldn't actually be creating virtual environments anymore.

You can track support for this in #7865
