Integrate RustRed Vakint with the modern HEPKit host Port the existing FeynKit tensor bridge and namespace/citation infrastructure from GammaLoop 8f834d9, retaining the shipped RustRed reduction artifacts and master catalogs. Bind both RustRed packages to audited 986c427f with default features disabled and the shared Symbolica 98794d0 graph. Expose native rich views without numerical f64 round-trips and add a FORM-invalid H rank-four reference gate. Keep Python rich-view acceptance in the actual installed host, and update two existing test fixtures with explicit uncut order metadata. Selected release-profile cargo check with community bindings and all test targets passes; numerical host acceptance remains separate. Co-authored-by: Codex <noreply@openai.com>
