Compares an asset's committed version (via `git show HEAD:<path>`) against the copy on disk and
reports the semantic delta: dependencies added/removed, asset-type changes, and Blueprint metric
shifts. Lets CI comment on what actually changed inside a `.uasset` in a pull request.

**Part of [uasset-lens](https://github.com/itsakeyfut/uasset-lens)** — a fast, CLI-first
static analyzer for Unreal Engine 5 assets that runs without opening the editor. This crate
provides HEAD-vs-disk asset diffing. Depends on: `uasset-lens-shared`. Used by: the uasset-lens CLI.

## Usage


```rust,no_run
use std::path::Path;
use uasset_lens_git_diff::diff_asset;
use uasset_lens_shared::AssetPath;

let asset = AssetPath::new("/Game/Characters/BP_Player")?;
let project_dir = Path::new("MyProject");
let content_root = Path::new("MyProject/Content");

if let Some(diff) = diff_asset(&asset, project_dir, content_root)? {
    println!(
        "+{} deps, -{} deps",
        diff.deps_added.len(),
        diff.deps_removed.len(),
    );
}
# Ok::<(), Box<dyn std::error::Error>>(())

```
