Derives the root Identity key from the 64-byte seed.
HKDF-SHA256(seed, salt = "", info = "me2em/identity/v1/root", 32)
(specs/v1.0.md §2–§3). This is the exact computation
Identity.fromSeed performs; exposed so advanced callers can
reproduce or audit the derivation without holding an Identity
instance.
