Encode a CAWG SignerPayload using c2pa_cbor in this instance's existing
worker. Hashes become CBOR byte strings; the wire keys are
referenced_assertions, sig_type, and (when nonempty) role. The payload is
copied to the worker, so encoding does not detach the caller's hash buffers.
Only the instance's worker capability is required; wrappers may replace or
omit its reader and builder factories.
Input names are case-sensitive: referencedAssertions, sigType, roles, and each
reference's url, hash, and alg. Wire-format names are not aliases. Missing or
incorrectly cased required fields are rejected; unknown data properties are
ignored, including incorrectly cased optional fields. Omitted, undefined, or
empty roles are omitted on the wire; null roles are rejected.
Use plain data objects with Uint8Array hashes. The entire payload, including
unknown properties, must be structured-cloneable. An unknown function
property that Node can ignore still causes a cloning failure here. Validation
and cloning failures reject the Promise; Node's validation throws synchronously.
Error types and messages are binding-specific.
