SPARK-proved HMAC (RFC 2104) with standalone SHA-256 (FIPS 180-4) for Ada 2022.
175 proof obligations fully discharged at Level 2 with zero pragma Assume.
Constant-time digest comparison (the default `=` operator), secure wipe of
key material, no heap allocation, pragma Pure. Suitable for embedded and
safety-critical systems. Includes streaming and one-shot APIs, plus a generic
HMAC package for other hash functions.
