Issue description

i'm currently playing around with pixi build and found that the package generated with pixi build doesn't include polars >=0.14.24,<0.21 in its dependencies, even though it's specified in pyproject.toml as well as pixi.toml.

Currently, index.json looks like this:

{
  "build": "pyhbf21a9e_0",
  "build_number": 0,
  "depends": [
    "python"
  ],
  "name": "polarify",
  "noarch": "python",
  "subdir": "noarch",
  "timestamp": 1732885543257,
  "version": "0.1.0"
}

Expected behavior

I would expect it to look more like this:

{
  "build": "pyhbf21a9e_0",
  "build_number": 0,
  "depends": [
    "python >=3.9", // from pyproject.toml requires-python or pixi.toml dependencies?
    "polars >=0.14.24,<0.21" // from pyproject.toml or pixi.toml?
  ],
  "name": "polarify",
  "noarch": "python",
  "subdir": "noarch",
  "timestamp": 1732885543257,
  "version": "0.2.0" // <- should be 0.2.0, from pixi.toml's package.version
}

Also, the package doesn't include a recipe file. Is this intended?

Did you specify the dependencies with [run-dependencies]?

[dependencies] is used by the workspace. [run-dependencies] specifies the run dependencies of the package. If you then include

[dependencies]
polarify = { path = "." } 

[run-dependencies]
python = "*"
polars = "*"

It should work. Note that this doesnt work with features. We are looking into using a form of variants to make that work properly.

makes sense, thanks!

[run-dependencies] is currently not in the schema yet; we should add it there

Also, the package doesn't include a recipe file. Is this intended?

It should contain a finalized recipe file eventually but not a recipe.yaml file because we don't explicitly create that.
