Improve build and install system

[reeceomahoney]

There are a mix of build systems being used in this project, with pyproject.toml and setup.py files and the root pyproject not being used to install packages in faovur of the install script. Have you considered updating IsaacLab to only use pyproject.toml files and centralising all the installation commands in the root project so only a single command is needed to setup the whole project. I have made this change in my own project, along with switching to uv instead of conda as a package manager and it has made setting up my projects on new machines much easier. I would be open to submitting pull requests if you think this is something worthwhile.

Hi @reeceomahoney , how did you manage to get uv to install IsaacLab? It seems that in the ./isaaclab.sh script it is explicitly checking for conda, and overriding python executable also does not work for me....

[reeceomahoney]

I'm using the following pyproject.toml to install everything. Don't need to run the install script at all.

What if I want to use UV to install IsaacLab? How should I do it? Thank for answering

[reeceomahoney]

Taking the Isaac related things from the pyproject file I linked above and just running uv sync should work.
