export
Reconstructs the full private key from the parties' shares — the way to move a key out of MPC, or to back it up.
The result is the raw private key — treat it with the same care as any private key and encrypt it at rest. Bring it back under MPC later with import.
Return
the reconstructed raw private-key bytes.
Parameters
keyId
the hex-encoded keyId to export; the SDK reads the share from its StorageClient.
