Request: Add `pixi.toml` Support for Reproducible ROS 2 Builds

[mhyatt000]

Would you be open to adding pixi.toml support to this repo?

Pixi gives fully reproducible, cross-platform ROS 2 environments with:

• deterministic builds (locked versions, no drift across machines),
• isolated per-project environments (no colcon-pollution from system ROS installs),
• fast, sandboxed builds for CI and local development,
• easy multi-platform setup

This would make xarm_ros2 dramatically easier to set up, especially for researchers and students onboarding to the package.

I'm happy to help in this regard if pixi is a good fit.

Hi @mhyatt000, thanks for the suggestion. We are not quite familiar with pixi and the workload required to support it yet, and may need some time to catch it up. Have you run into any trouble if it is not supported?

[mhyatt000]

currently, i am using pixi to manage system dependencies in place of rosdep... but i recall from reading the docs, that there might be a way to package the xarm repo so that users could simply
pixi add xarm or conda install

[mhyatt000]

so i havent run into any trouble in my case, but i have not tried to repackage anything

[mhyatt000]

looking into this. and will keep you posted soon
