"""Tools — Monitoring tab (Admin) to govern every agent capability.

Two sub-tabs:
  * "Tool"      — built-in agent tools (read/write/edit files, run commands,
                  install packages, fetch URLs) as a left-aligned card grid;
                  toggling one OFF removes it from the agent's toolset
                  (persisted in ``config.tools_disabled``).
  * "Connector" — the full Connectors (MCP / REST API) setup, moved here from
                  Settings: add/edit/delete CAD/CAE/MS365/Other connectors and
                  enable/disable each (``ConnectorsPanel``).
