Show HN: fh, the FlakeHub CLI

Hey HN, after we launched FlakeHub last week, a common question was: what about the CLI? We heard you loud and clear, and here's a scrappy first pass at a useful fh CLI tool.

It supports searching and adding inputs to your flake, plus a few other things. In the future, it'll do more -- like publishing.

I'll be here to answer questions, but what would you like to see it do?
