* Augments the digest field of errors thrown in React Server Components (RSC) with an error code.
* Since RSC errors can only be serialized through the digest field, this provides a way to include
* an additional error code that can be extracted client-side via `extractNextErrorCode`.
*
* The error code is appended to the digest string with a semicolon separator, allowing it to be
* parsed out later while preserving the original digest value.
