Note

Medium Risk
Adds a new transaction type/flow (SUI) to the Rango swap plugin, which affects quote-to-transaction construction and could break swaps if the upstream payload or decoding assumptions are wrong.

Overview
Adds SUI support to the rango DEX plugin by accepting tx.type: 'SUI' responses and converting Rango’s unsignedPtbBase64 into a MakeTx flow (using base64 decode) with swap metadata.

Refactors swap order construction to reuse a common swapOrderBase (shared metadataNotes/expiration/etc.) across EVM/Solana/Cosmos/Sui, and updates the CHANGELOG with the new capability.
