codec/kat.go: KATEntry + KATBundle types with canonical JSON
serialization. Header field embeds params.KATHeader so every entry
carries (parameter_set, modulus_id, backend_id, hash_suite_id,
implementation, version) — required by LP-107 §"Parameter registry"
for cross-runtime equality.
codec/cmd/emit_codec_kat/main.go: emits 5 canonical entries:
1. ReadUint64Slice/happy-path/3-elements
2. ReadUint64Slice/empty
3. ReadUint64Slice/reject/lattice-issue-4-70T (regression: huge
length must be rejected by both runtimes)
4. ReadUint16Slice/happy-path/5-elements
5. ReadUint32Slice/happy-path/4-elements
Each entry records:
- InputHex: the wire-format bytes the Reader consumes
- OutputHex: the canonical output byte stream (or "REJECTED")
- OutputSHA256: commitment for fast cross-runtime equality
codec/kat_test.go: TestKATBundle_RoundTrip replays every bundle
entry through the Go Reader and asserts byte-equality + SHA-256
commitment match. PASS in 0.29s.
codec/testdata/codec_kat.json: the Go-emitted bundle. The C++ side
at luxcpp/crypto/math/test/codec_cross_runtime_test.cpp loads the
same file and replays every entry; in this commit, all 5 entries
PASS byte-equal between runtimes.
This closes LP-107 Phase 7 for codec/. Subsequent commits extend the
gate to modarith/, ntt/, poly/, sample/ KATs.
