/**
 * Builds the shared asset-funding actions — native wrapping followed by the ERC-20 pull — that move
 * `asset` into `GeneralAdapter1` before a bundled Morpho operation (`blueSupply`,
 * `blueSupplyCollateral`, `blueSupplyCollateralBorrow`, `blueRepay`, `blueRepayWithdrawCollateral`).
 *
 * Encode-only and synchronous: returns a fresh `Action[]` (never mutates its inputs, mirroring
 * `buildVaultV2BlueReallocationActions`) and reads no on-chain state. When `nativeAmount > 0n`, validates
 * `asset` is the chain's wNative and emits `nativeTransfer → wrapNative`. When `erc20Amount > 0n`,
 * pulls the ERC-20 via a signed permit/permit2 (`requirementSignature`) or a plain
 * `erc20TransferFrom` — `getTokenRequirementActions` emits the latter itself when no signature is
 * supplied. A fully-native funding emits no ERC-20 action; funding nothing returns `[]`.
 *
 * Single source of truth for the native-wrap + ERC-20-pull composition every bundled Blue funding
 * path depends on — a fix here applies to all of them instead of risking a silent divergence
 * between copies.
 *
 * @param params - See {@link BuildAssetFundingActionsParams}.
 * @returns The `nativeTransfer`/`wrapNative`/pull actions, in bundle order (empty when nothing is
 *   funded).
 * @throws {ChainWNativeMissingError} when `nativeAmount > 0n` but the chain has no configured wNative.
 * @throws {NativeAmountOnNonWNativeAssetError} when `nativeAmount > 0n` but `asset` is not the
 *   chain's wNative.
 * @throws {DepositAssetMismatchError} from `getTokenRequirementActions` when `requirementSignature` is
 *   provided and the signed asset differs from `asset`.
 * @throws {DepositAmountMismatchError} from `getTokenRequirementActions` when `requirementSignature` is
 *   provided and the signed amount differs from `erc20Amount`.
 * @throws {Permit2ExpirationMissingError} from `getTokenRequirementActions` when a Permit2 requirement
 *   signature is missing its expiration.
