Function print_load_status 

pub fn print_load_status(
    from_cache: bool,
    module_count: usize,
    elapsed_ms: f64,
    file_warnings: &[String],
    unresolvable_dynamic_count: usize,
    unresolvable_dynamic_files: &[(PathBuf, usize)],
    root: &Path,
    sc: StderrColor,
)

Print the standard graph-load status line plus any warnings.

Used by the CLI (trace, packages, diff) and the REPL startup to avoid duplicating the same formatting logic.
