saves wrong path for external asset.

cargo is a blueprint in another file which is correctly exported to blueprints/cargo.glb, but when I save my level it puts in the wrong path, causing a crash. ``` "extras": { "SpawnBlueprint": "()", "BlueprintInfo": "(name: \"cargo\", path: \"./cargo\")" }, "name": "cargo", ``` ``` 2025-03-22T21:56:43.211051Z WARN blenvy::blueprints::spawn_from_blueprints: FAILED TO LOAD ./cargo 2025-03-22T21:56:43.211262Z INFO blenvy::blueprints::spawn_from_blueprints: Step 3: all assets loaded, attempting to spawn blueprint scene BlueprintInfo { name: "cargo", path: "./cargo" } for entity Some("cargo"), id: 90v1 thread 'Compute Task Pool (7)' panicked at forks/Blenvy/crates/blenvy/src/blueprints/spawn_from_blueprints.rs:472:2025-03-22T21:56:43.211299Z ERROR bevy_asset::server: Path not found: ./cargo 13: gltf file "./cargo" should have been loaded ```
