Subject: [PATCH] Fix inefficient copy warning by using self instead of ./. in
 nix derivation

As suggested by the Determinate Nix changelog, replace the relative path
reference with the flake's self input to avoid unnecessary copying to
the store. This improves evaluation performance and reduces file copies.
