/**
 * Wire shape for errors thrown across the RPC boundary. The fields are
 * the union of (a) the legacy `QvacErrorBase` serialisation (`name`,
 * `code`, `message`, `stack`, `cause`, `timestamp`) and (b) the new
 * `typedFields` map (0.11.0+) carrying per-class structured data the
 * client-side reconstructor uses to rebuild the original typed error.
 *
 * `typedFields` is opaque on the wire — `z.unknown()` — and the
 * per-class reconstructor in `client/rpc/rpc-error.ts` casts each
 * member at the boundary. The single-map shape keeps the schema
 * compact regardless of how many typed-error classes the SDK
 * eventually surfaces across RPC. New typed-error classes that need
 * cross-RPC reconstruction add a `toErrorResponseFields()` method on
 * the server side and a row to the reconstructor map on the client
 * side; the schema itself doesn't change.
