SPARK-proved HKDF (RFC 5869) for Ada 2022, built on `hmac_ada`. The
HKDF-SHA-256 instantiation is fully proved at SPARK Level 2 (266 checks,
zero `pragma Assume`). Uses `System.Storage_Elements.Storage_Array` for
embedded and constrained-runtime (Light, ZFP) compatibility, no heap
allocation, `pragma Pure`. A separate generic `HKDF` package provides an
unproved convenience layer for other HMAC functions.
