v0.6.0 — full 20-endpoint signed absorption Absorbs every wrapped-JSON /...-signed endpoint chain shipped on 2026-05-03 in one drop (per all-signed-endpoints-shipped.md): - 18 single-sig SignedXxxAsync methods on VelocityClient - 2 §18 committee-quorum SignedCommitteeQuorumForce*Async methods - SignedActionEnvelope.BuildQuorum + CommitteeQuorumSignature - SignedEndpointRegistry (20-entry kind→path map) - Response DTOs (SignedActionWriteResponse, CommitteeQuorumSignedResponse) - New domain tags + 9 borsh payload structs (Mint/Burn/RegSession/ RevokeAcct/GrantCap/Grant+RevokeCrossNs/4×§18/FlashSwap) - Tests for envelope, registry, response DTOs, and every borsh layout The two legacy binary-envelope endpoints (register-signed, add-key-signed) keep their original shape; SDK still routes to them via the existing identity flow.
