hred: convert to finalAttrs, add binlore

[tejing1]

• Added binlore entry to ease use in resholved scripts.
• Converted to finalAttrs since buildNpmPackage supports that now.
• Using finalAttrs.finalPackage ensures that the binlore passthru corresponds correctly even when the package is overridden outside of an overlay, which otherwise wouldn't be possible. (tests, too... though that's not all that important)

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• Nixpkgs 25.11 Release Notes (or backporting 24.11 and 25.05 Nixpkgs Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
• NixOS 25.11 Release Notes (or backporting 24.11 and 25.05 NixOS Release notes)
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other contributing documentation in corresponding paths.

I suppose I should clarify a bit, for reviewers not familiar with resholve and binlore. There are 3 things that need to be verified about this PR:

• That the conversion to finalAttrs was done correctly without some kind of mistake.
• That the binlore passthru is properly formed and is picked up by resholve. You can test this by trying to use hred in a resholve-packaged shell script.
  Try building something like this: pkgs.resholve.writeScript "hred-test" { interpreter = lib.getExe pkgs.bash; inputs = [ pkgs.hred ]; } "hred --version"
  The build will fail with a complaint about missing lore on current nixpkgs, but succeed with this PR.
• That the assertion is actually correct. That is, that hred never runs any of its arguments as commands, and thus resholve doesn't need to worry about translating any of them to absolute paths. This is quite easy to see from hred's --help output. It has a very simple interface, with no commands in sight.
