Function create_math_intrinsics_module 

pub fn create_math_intrinsics_module() -> ModuleExports

Create the math intrinsics module with 14 typed-marshal entry points. The 4 polymorphic intrinsics (min, max, char_code, bspline2_3d_batch) remain as legacy IntrinsicFn bodies in this module until their follow-on architectural sub-decisions land. sum was deleted by W12-stdlib-intrinsic-collapse (Wave-2-Agent-G, 2026-05-14) — stdlib now routes through PHF .sum() method dispatch.
