/**
|
||
|
|
* Wrap whatever the generated client decoded from a non-2xx error body
|
||
|
|
* into a real `Error` so downstream formatters (TUI, plugins) get a
|
||
|
|
* useful `.message` instead of `[object Object]` or blank. The original
|
||
|
|
* parsed body and status live under `.cause` for callers that need
|
||
|
|
* structured fields.
|
||
|
|
*
|
||
|
|
* Only fires when the caller used `{ throwOnError: true }`. Callers that
|
||
|
|
* read `result.error` directly (the result-tuple path) get the parsed
|
||
|
|
* body unchanged so existing field-level reads (`.error.name`,
|
||
|
|
* `JSON.stringify(error)`, etc.) are byte-for-byte identical to before.
