Function default_output_dir 

pub fn default_output_dir(
    config: &ResolvedCrateConfig,
    default: &str,
) -> PathBuf

Resolve the per-backend output directory for generated files.

This helper wraps resolve_output_dir with a sensible default for C-FFI consumers, allowing backends to pass a language-specific default (e.g., “packages/go/”, “packages/java/src/main/java/”).

Arguments

• config: The Alef configuration.
• default: The backend-specific default output directory (e.g., “packages/go/”).

Returns

A PathBuf representing the resolved output directory.
