just for command runner (instead of make)

[pjbull]

just is a tool for storing and running project specific commands.

Github: https://github.com/casey/just
Documentation: https://just.systems/man/en/

Pros:

• Standalone binaries for all platforms
• Simple syntax
• Ability to create DAG
• Seems pretty actively maintained
• Supports .env files

Cons:

• Not preinstalled in most environments
• Not common enough that people will have experience already

make scares people, especailly of Windows, and I find https://github.com/casey/just command runner super helpful. it enables learning and you can try simple commands and extend them, extremely well-thought tool.

It looks like someone made a PyPI package for distributing the Just binary. https://pypi.org/project/just-bin/

This means we could have it be a dependency for CCDS-generated projects. Though one would still need to install it first before being able to use it to manage project tasks.
