Subject: [PATCH] packages/overlays: use builtins.readDir for dynamic package
 discovery

Instead of manually listing packages, the overlay now reads the
packages/ directory and automatically includes all .nix files
(except overlays.nix itself) as overlay attributes.

This makes adding new packages simpler - just add the file and it
will automatically be included in the overlay.
