Test helper API for accessing downloaded World of Warships game data.

Use these functions in integration tests to get VFS access to game builds. Tests should skip gracefully when game data is unavailable.

Example

use wows_data_mgr::{available_builds, vfs_for_build};

#[test]
fn test_game_params_load() {
    let builds = available_builds();
    if builds.is_empty() {
        eprintln!("Skipping: no game data available");
        return;
    }
    for build in builds {
        let vfs = vfs_for_build(build).unwrap();
        // test with vfs...
    }
}
