Motivation:
Add SCRAM-SHA-256 HTTP authentication (RFC 7804) — mutual password-based auth with PBKDF2 key derivation that never transmits the password over the wire.
Modification:
Add SCRAM_SHA_256 to AuthScheme, ScramEngine for crypto (PBKDF2, HMAC-SHA-256, RFC 7613 password normalization), ScramContext for per-exchange state, ScramSessionCache for reauthentication, and ScramMessageParser/ScramMessageFormatter for RFC 5802 wire format.
Result:
Added RFC 7804 SCRAM-SHA-256 support with 94 tests, 0 regressions.
