Reduce Nix flake maintanace by eliminating need for cargoHash bumps (#3292)

* prepare nix for hashless cargo builds, update rust-gpu to non-orphaned
commit

* match commit hashes to repos, update packages to make nix flake build
properly

* add nix build dir to gitignore

* Add npm TODO to flake.nix

* Update Cargo.lock

* Update TODO comment
