Verify a home-manager package landed by filtering evaluated home.packages

After adding a package to a flake-parts homeModule, confirm it reaches a host without rebuilding: nix eval --raw '.#nixosConfigurations.<host>.config.home-manager.users.<user>.home.packages' --apply 'ps: builtins.concatStringsSep "\n" (map (p: p.name) (builtins.filter (p: (p.pname or "") == "<pkg>") ps))'. It also shows the version from the flake's pinned nixpkgs, which can differ from nix eval nixpkgs#<pkg>.version (registry). Example: nixpkgs late 2026 has anki 26.08 (source build) and anki-bin 26.05 (upstream binary).
