Subject: [PATCH] chore(nix): remove flake-parts dependency

Simplify flake.nix by removing flake-parts and using standard
nixpkgs.lib.genAttrs pattern instead. The devShell configuration
is simple enough that flake-parts adds unnecessary complexity.

- Remove flake-parts input
- Use forAllSystems helper with genAttrs
- Maintain identical functionality
