Function load_compile_deps 

pub fn load_compile_deps(
    items: &[TopLevel],
    module_root: &str,
) -> Result<Vec<ModuleInfo>, String>

Load every dep module declared by items’s Module.depends, plus every transitive dep, into codegen::ModuleInfo records ready to hand to PipelineConfig.dep_modules.

Each dep goes through the same canonical pipeline as the entry — pipeline::run with TypecheckMode::Full { base_dir: module_root }, run_interp_lower: false, run_buffer_build: false, and the neutral alloc policy. Type errors in any dep surface as Err.

Callers that need the legacy commands.rs shape (run_interp_lower / run_buffer_build / self_host_mode flags) still own their local copy; every other call site — vm_verify, wasm_gc_verify, bench/runner, the research test — should go through here so the dep-loading contract stays in one place.
