emit_codec_kat — produces the canonical cross-runtime KAT bundle for luxfi/math/codec. The C++ side at luxcpp/crypto/math/test/ codec_cross_runtime_test.cpp reads the same JSON and asserts byte-equal Reader behavior on every entry.

LP-107 Phase 7: Go emits → C++ verifies. This is the first cross-runtime release gate for the math substrate.

Usage:

go run ./cmd/emit_codec_kat --out testdata/codec_kat.json
