Suggests

• ext-opcache: Significantly speeds up the pure-PHP post-quantum fallback when ext-pqcrypto is not available (enable JIT).
• ext-pqcrypto: Native C implementation of ML-KEM/ML-DSA (github.com/paragonie/ext-pqcrypto). Strongly recommended in production: faster and side-channel resistant. Compat uses it automatically when loaded.
