pub fn load_layers(layers: &[PathBuf]) -> Result<MissionConfig>Expand description
Merge the given config files (in order, later wins) over the compiled-in defaults. Exposed so callers (and tests) can supply explicit layer paths instead of the real home directory.
Every layer is treated as Layer::Global: an explicit-path caller is
the operator (or a test), not a repository. Use
load_layers_with_roles when a layer’s provenance matters.
