0.4.1 Patch release for the Phase 3-6 wire-shape corrections from chain's reply at siblings-comms/unity-sdk/phase-3-6-wire-shapes-and-custodial- confirmed.md. Fixed: - SwapPool / AmmPool DTOs: flat token field pairs (token_in_namespace + token_in_name etc) instead of nested TokenId. - SwapPool: lifetime fields renamed to lifetime_input_burned / lifetime_output_minted. - AmmPool: dropped unconfirmed lifetime fields. - All Phase 3-6 request bodies: flat token fields. - CreateAmmPoolAsync: dropped initial_liquidity_a/b which the chain doesn't accept. Breaking: - PurchaseCapabilityAsync now requires adminKeyHex + adminSignatureHex parameters (no custodial mode). Caller produces these externally via velocity-wallet or a future Borsh+Ed25519+Blake3 stack.
