* Fix: Prevent side effects in `processMCPEnv` by deep cloning MCPOptions
The `processMCPEnv` function was modifying the original `MCPOptions` object, leading to unintended side effects where `LIBRECHAT_USER_ID` could be incorrectly shared across different users. This commit addresses this issue by performing a deep clone of the `MCPOptions` object before processing, ensuring that modifications are isolated and do not affect other users.
* ci: Add tests for processMCPEnv to ensure deep cloning, user ID isolation and environment variable processing
