Nix is probably the best way to get all of those things set up without shipping a whole distro, but there will be a bit of a learning curve. If you’d like something a bit easier to set up for development (still based on Nix), I’d recommend devenv.sh.

Maybe Discourse? The mobile website is pretty good and there are also a number of third-party mobile apps.

I really like immutable distros, and am currently using NixOS. I feel like despite still being relatively obscure, NixOS is a bit of an outlier since it has more packages than any other distro and is (so far) the only distro I’ve used that has never broken. There is a steep learning curve, and I certainly wouldn’t recommend it for non programmers, but it is something truly different than all mainstream Linux distros while being extremely reliable.
