Reject malformed ML-DSA signing inputs

Summary

  • Reject short external-mu inputs before copying mu in internal signing and verification.
  • Reject nonzero context length with a NULL context pointer at the domain-separation prefix boundary.
  • Add focused unit regression tests for the malformed external-mu and domain-prefix cases.

Verification

  • Pre-fix make run_unit_44 failed after adding the targeted malformed-input regression test.
  • make run_unit_44
  • make run_unit
  • make run_func

Note: the focused regression test and broader unit/functional runs above were collected on the tidy pre-replay patch commit. This PR branch was then cleanly replayed onto current upstream main; post-replay git diff --check passes, but the tests have not been rerun on the replayed commit yet.

Reject short external-mu inputs before copying mu in internal signing and
verification, and reject nonzero context length with a NULL context pointer
at the domain-separation prefix boundary.

Add focused unit regression tests for the malformed external-mu and
domain-prefix cases without bundling unrelated SHAKE/output-cleanup tests.

Verification:

- pre-fix `make run_unit_44` failed after adding the targeted malformed-input
  regression test

- make run_unit_44

- make run_unit

- make run_func

Keep the signing-side short external-mu unit regression test enabled when the build exposes keygen and sign APIs but compiles out verification. Guard only the verify-side malformed external-mu assertion so reduced-api keygen+sign builds do not reference verify_internal.

Verification:

- pre-fix focused reduced-api unit check failed with an implicit declaration of verify_internal under MLD_CONFIG_NO_VERIFY_API

- focused reduced-api unit check passed for keygen+sign/no-verify

- focused reduced-api-reduce-ram unit check passed for keygen+sign/no-verify

- nix develop .#ci -c lint
