Subject: [PATCH] nix: name the crane derivations, instead of "cargo-package"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The root manifest is a pure [workspace], so crane finds no [package].name
to name its derivations after and falls back to a placeholder — every
build of crabidy logged two "crane will use a placeholder value" warnings
and produced cargo-package-0.1.0.drv, which says nothing about what was
built.

Name it in [workspace.metadata.crane], the spelling crane itself
suggests. Cargo ignores unknown workspace metadata, so this is a build
label and nothing more.

The cross build takes its name from the same root, which would leave the
native and aarch64 derivations both called crabidy-0.1.0; give it an
explicit pname so a build log can tell them apart.
