geldata/gel ? reverse-engineered prompt

Help me get this Gel project building and running locally from source, then make sure I can actually use it end to end.

I want a simple setup where the database starts, I can create a tiny schema for something like movies and people, and I can run a few example queries in the interactive shell to prove it works. Please wire up whatever is needed so the build succeeds, the command line tool is usable, and the basic tests or checks that make sense for a fresh checkout pass.

If there are any current setup steps that are easier to follow from the latest docs, look them up online and use the newest guidance. Keep it straightforward and make it feel like a clean first time experience for someone trying this project out locally.
