PendingArkTransaction: A pending Arkade transaction the server is holding open: the user submitted it via SubmitTx(string, string[], CancellationToken) (which made the server lock the inputs as "in-flight") but the matching FinalizeTx(string, string[], CancellationToken) never landed. Returned by GetPendingTxAsync(string, string, CancellationToken) so the SDK can sign the checkpoint PSBTs and finalize on the next startup, releasing the user's coins.

VtxoChainEntry: A single entry in a VTXO's virtual transaction chain. Chains returned by GetVtxoChainAsync(OutPoint, string?, string?, CancellationToken) are ordered leaf -> root: the VTXO's own tx first, ending at the on-chain Commitment anchor.
