feat: Add versions/build list to pixi search output

[delsner]

Motivation

Different to e.g. micromamba search, pixi search does not provide information about other versions/builds of the found package (xref #378).

Changes

Add versions/builds list for pixi search output.

Joint work with @pavelzw.

[pavelzw]

pixi search polarify

pixi search conda-forge-pinning (long versions)

pixi search polars (multiple builds for newest version)

Thanks for this great improvement!

This looks great already, what makes it draft for you?

[delsner]

The PR still lacks adequate testing. I want to include that before marking it as ready to review.

[delsner]

@ruben-arts feel free to take a look! I'm a rust newbie, so please let me know if I'm violating any code conventions.

Just FYI I also had a little stab at revamping the whole search topic here: #2390

If you want to incorporate anything from there, feel free! :)

[pavelzw]

@wolfv yes we plan to improve pixi search in a series of PRs to eventually have it in a way that we can close #378 :)

[ruben-arts]

Thanks for the contribution! I like the output improvements and the idea of the list of builds. The code looks good to me.

For the tests I would like to have them less hardcoded to make it more friendly to developers touching other parts of the code and then breaking these tests.

I love it! No more remarks
