Subject: [PATCH] fix: set HOME in sbom Nix build so syft can create its cache
 dir

In the Nix sandbox HOME points to a nonexistent /homeless-shelter,
so syft fails to create $HOME/.cache/syft (permission denied) and
exits without producing the sbom.cdx.json output, breaking the
"Generate SBOM (CycloneDX)" CI job.
