Measure at which levels Nx knows about dependencies

Nx file map carries a per-file deps field, which would be dependency
information below the project level. It is empty for every TypeScript file in
this workspace: 88 tracked, 0 carrying deps. All 16 deps-carrying files are
package.json.

So in a pnpm workspace Nx knows dependencies at exactly one level, project to
project, derived from the manifests. That is the same derivation nix/graph.nix
does at evaluation time, which is why the two match exactly.
