👷 init crane

[a-kenji]

Use crane to build crates, since it drastically improves caching behavior.

This builds:

• centerpiece
• index-git-repositories

Also includes a checks attribute, that will build centerpiece, index-git-repositories and an unobtrusively configured clippy check that can be run with nix flake check.
