Describe the bug

I'm using the latest opensea-js SDK (8.0.5) and encountering an error when calling the fulfillOrder function.

Error:

TypeError: unknown function (argument="fragment", value="fulfillBasicOrder_efficient_6GL6yc", code=INVALID_ARGUMENT, version=6.15.0)

Context:
After some debugging, it seems that opensea-js depends on @opensea/seaport-js@4.0.5 (which is also the latest version).
The error occurs in opensea-js/src/sdk/fulfillment.ts at line 210:

const encodedData = seaportInterface.encodeFunctionData(
  functionName,
  params,
);

The issue appears to be that the Seaport ABI provided by @opensea/seaport-js does not include the method fulfillBasicOrder_efficient_6GL6yc, which is being referenced by opensea-js.

Expected behavior:
fulfillOrder should correctly encode and execute the fulfillment transaction without throwing a missing function error.

Environment:

opensea-js: 8.0.5
@opensea/seaport-js: 4.0.5
ethers: 6.15.0

Additional notes:
It looks like opensea-js may be attempting to use a Seaport contract version whose ABI differs from the one bundled in @opensea/seaport-js. Updating the ABI or function mapping might resolve this mismatch.
