"funded": broadcast a splitter at prepare time and pre-sign the
fee children — the package executes fully keyless."graph": transport only the tx graph + sweeps; the executor funds
and signs the CPFP bumps at execution time ("send funds to this
address and we proceed"). No splitter, no onchainWallet funds used.OptionalnetworkNetwork label embedded in the package (executor sanity check).

Fee funding source and change/funding address. Must share the wallet identity.
Destination for the exited funds.
OptionalvtxosDefaults to all spendable VTXOs.
Wallet owning the VTXOs: identity (signing) + indexer + onchain provider.
sat/vB; defaults to the onchain provider estimate, floored at MIN_FEE_RATE.
