Cannot build because CREATE_NO_WINDOW is never used

**Describe the bug**

When installing gitui with nix on my env, it does not build.

```
$ nix profile upgrade --all
warning: Found package 'nix', but it was not added from a flake, so it can't be checked for upgrades!
warning: download buffer is full; consider increasing the 'download-buffer-size' setting
error: Cannot build '/nix/store/pa5r9f6lmfwqc54ly1k600njql1si3wh-gitui-0.27.0.drv'.

For full logs, run:
nix log /nix/store/pa5r9f6lmfwqc54ly1k600njql1si3wh-gitui-0.27.0.drv
```

**To Reproduce**

1. Install nix user installation
2. Install gitui with nix

**Expected behavior**

It should build.

**Context (please complete the following information):**
- OS/Distro + Version: Rocky Linux 9.3
- GitUI Version 0.27.0
- Rust version: rustc 1.84.0 (9fc6b4312 2025-01-07)
- nix channel https://nixos.org/channels/nixpkgs-unstable

**Additional context**

gitui is very increadibly amazing, thank you for making it, it is the best.

Inspect git2-hooks/src/hookspath.rs around line 214 and the dead_code lint setting in git2-hooks/src/lib.rs around line 16. Reproduce the failure with the Nix installation described in the issue, then verify that the project builds without the unused CREATE_NO_WINDOW error.
