fix(nix): resolve build failures in the nix flake (#1068)

This pr resolves two build failures when using the nix flake.

### flake inputs

Some pkgs where outdated, thus causing a build failure.
Fixed by updating the `flake.lock` file.

### Check phase

After building the pkg, the tests are ran in the check phase. This phase
failed because it required some pkgs that the flake was not providing:
`zoxide` and `exiftool`.
Fixed by adding those pkgs to the `nativeCheckInputs`.

## Summary by CodeRabbit

- Chores
- Updated build/check dependencies for the superfile package, adding
additional tools to the validation environment. This affects development
and CI only and does not alter runtime behavior or the user experience.

- Tests
- Expanded the check environment with supplementary tools used during
package checks. No user-facing changes.
