feat: update to zig 0.13.0 (#24)

* chore: update flake.lock

Flake lock file updates:

• Updated input 'nixpkgs':
    'github:NixOS/nixpkgs/9bb1e7571aadf31ddb4af77fc64b2d59580f9a39' (2024-09-05)
  → 'github:NixOS/nixpkgs/268bb5090a3c6ac5e1615b38542a868b52ef8088' (2024-09-19)
• Updated input 'zig-overlay':
    'github:mitchellh/zig-overlay/9e2cc0e99621be1b765dc95a8ec80740a685b660' (2024-09-06)
  → 'github:mitchellh/zig-overlay/2419eb9f968f451e2c342a69ec44112de5aa36b9' (2024-09-21)

* style: use nixfmt

* style: format with nixfmt

* refactor: use flake-utils

* fix: only use `zig` in dev shell

Pulling in `zig.hook` sets variables like `ZIG_GLOBAL_CACHE_DIR` that
don't work too nicely outside of a Nix build process -- as in, Zig can't
access files and fails

* feat: update to zig 0.13.0

* chore: remove library output

This isn't needed for this example
