fix: register tools via setTools(), add Tools/Code capability badges

- Fix 'Tool browser not found': createTools callback was silently ignored
  by Agent constructor. Now uses agent.setTools() after instantiation.
- Add Wrench (Tools) and Code icons + filter buttons to ModelSelector
  alongside existing Brain (Reasoning) and Image (Vision).
- Add refreshSidebar() call in createAgent for session list updates.
