The store pin changed package-lock.json, so the workspace-wide
npmDepsHash in nix/lib.nix is stale and the Nix flake check fails on
the hash mismatch. Use the hash reported by the real fetchNpmDeps
build (the flake check's `got:`), which is authoritative — it differs
from prefetch-npm-deps' lockfile-contents hash, exactly the divergence
nix/lib.nix already documents.
