chore: remove backward compatibility comments

Removed backward compatibility comments from codebase as we are in alpha phase without released users. Kept the actual compatibility code in place, only removed explanatory comments.

Changes:
- Removed comments from __init__.py (ToolBase alias)
- Removed comments from module.py (call_super_init, aforward fallback)
- Removed comments from tool.py (mcp_clients storage)
