 * Registry for AnyPublicKey and AnySignature variant handlers.
 *
 * This allows keyless (and future) variants to register themselves at runtime,
 * so that singleKey.ts does not need a compile-time dependency on keyless/poseidon.
 * When the keyless module is imported, it registers its deserializers and instanceof
 * checkers here. If keyless is never imported, these variants remain unregistered
 * and deserialization will throw a clear error.
