+    Regression coverage for two bugs found while building a ML-KEM/ML-DSA

+    0 exit code instead of failing loudly:
+
+      1. `req -new [-x509] -key <ml-dsa priv>` failed to embed the
+         certificate's public key, because wolfSSL's ML-DSA private-key
+         decode does not recompute the public key from imported private-key
+         components. Fixed in wolfSSL by having
+         wc_MlDsaKey_PrivateKeyToDer() include the public key in the
+         RFC 5958 OneAsymmetricKey `publicKey [1]` field.
+      2. `ca -in <csr> -keyfile <ml-dsa priv> ...` silently skipped the
+         signing step for any non-RSA/ECDSA CA key (wolfCLU_GetTypeFromPKEY,
+         wolfCLU_CertSignSetCA, and wolfCLU_CertSign only recognized
+         RSAk/ECDSAk), yet still wrote out a certificate file and exited 0;
+         the file was missing its issuer name and validity dates and failed
+         to parse. Fixed by recognizing ML-DSA keys in those three
+         functions.
