Describe the bug

Building this project with Nix currently fails for three reasons:

1. The dependency hash in flake.nix is out of sync with the project's Go dependencies, causing the build to fail due to a hash mismatch.
2. The scard dependency now requires CGO, which is disabled in flake.nix.
3. The scard dependency has system-level dependencies that are not included in the Nix build inputs.

To reproduce

• Clone the project
• Have nix installed/available locally
• nix build

Expected behavior

The project should output a result symlink into the nix store containing the resulting matcha binary.
