The off-chain byte-mirror now speaks V2/188: max_revolving_capacity (the credex
revolving-capacity admission cap) is passkey-endorsed at registration. The
message grew 180->188 (one u64 LE at [180..188)), domain OTS_SESSION_REGISTER_V1->V2,
and the register_session_key instruction carries it in Borsh order after nonce.
SessionScope gained optional revolvingCapacityAtomic (0.4.1).

Published to npm: 0.4.0 (core V2) + 0.4.1 (optional scope field).
34/34 byte-parity tests green. Proven against live mainnet program via the
dexter-vault register-session-key gate (tx 7n5X2y8R...).
