Rv, a new kind of Ruby management tool

The more tools the better. Thanks!

As an idea: add advantages compared to rvm, rbenv, etc. Or a comparison table

> Ruby Versions: Ruby 3.4.1 and up

It turns out that this is only for the latest ruby versions :(

But I will follow the development!

If I understand correctly, rvm/rbenv only install Ruby versions, and you use bundler to install dependencies. rv seems to manage everything (like uv in Python) – Ruby versions and dependencies, and adds things on top of that (like `rv tool` for global tools installation).
