Regenerate pixi.lock for xmas_app 0.11.0 with current pixi

FYI @tkraft

The original error:

Error:   x Failed to load lock file from `C:\Data\git\xmas-plugin\pixi.lock`
  `-> environment build and platform linux-64 refers to a package that does not exist: https://files.pythonhosted.org/packages/36/41/076530d1210f1fad5adbbff1ce1cc4b3ab15984fb0b8bd07af7a360e05e2/xmas_app-0.11.0-py3-none-any.whl

blocked the building of the pixi-env.

I was able to rule out:

1. 404 / missing artifact (200 OK, download).
2. Zscaler / proxy issues (curl from CLI works)
3. Recently changed wheel (Last-Modified is before the timeframe where it worked).

The error text itself explicitly says: “Failed to load lock file”, not “failed to download” or “no matching distribution”.

That all points to a stale / partially outdated pixi.lock combined with a stricter pixi/uv version, not a broken wheel.

So I deleted the pixi.lock file, created a new one and now it works again. Here's the updated file. @OC000081912074 bitte überprüfen, ob das auch bei dir unter Linux funktioniert.
