<SdkOption name="enhanceFetchErrorMessages" type="'always' | 'report-only' | false" defaultValue="always" availableSince="10.34.0">

Controls whether fetch error messages are enhanced by appending the request’s hostname. When enabled, generic fetch errors like "Failed to fetch" will be enhanced to include the hostname (e.g., "Failed to fetch (example.com)") to provide better context in Sentry.

Available options:

- `'always'` (default): Modifies the actual error message directly. This may break third-party packages that rely on exact message matching (e.g., `is-network-error`, `p-retry`).
- `'report-only'`: Only enhances the message when sending to Sentry. The original error message remains unchanged, preserving compatibility with third-party packages that also check error messages.
- `false`: Disables hostname enhancement completely.
