This fixes the issue where importing MCPClient would disable logging globally.
- Move logging configuration from module-level imports to BrowserUseServer.__init__()
- Add lazy import in __init__.py to avoid importing server module when only client is needed
- Create _configure_mcp_server_logging() function that only runs when server is actually used
- Environment variables now only set when BrowserUseServer is instantiated
Fixes#2449
