Major Bug Fixes

• Tool Loader Security Enhancement - PR#1214
  Added module name prefixing in the tool loader to prevent collisions between user-defined tools and Python system modules. This security enhancement protects against accidental or malicious tool names that could shadow critical system modules, improving the safety of dynamic tool loading.

• MCP Connection Resilience - PR#1231
  Enhanced MCP client stability by implementing error filtering for recoverable client-side errors. The client now properly handles "unknown request id" errors that occur when responses arrive after client-side timeouts, preventing unnecessary connection termination while maintaining proper error handling for genuine server failures.
