feat: enhance error handling and logging in proxy and response management

- Added error stack and cause fields to the message request schema for improved debugging of TypeError: terminated and other stream errors.
- Updated the ProxyForwarder to use error-tolerant fetching for all providers, enhancing resilience against stream termination issues.
- Enhanced logging to capture detailed error information, including stack traces and causes, while ensuring that overly long messages are truncated for manageability.

These changes improve the robustness and maintainability of error handling in the application.
