- Active Tab: Now uses `FontWeight::BOLD`, `text_base()` font size, and the primary theme color. This makes it far more distinct from inactive tabs, especially in themes where background differences are subtle.
- Settings Dialog: Overrode the default sidebar style to use the main dialog background (`cx.theme().background`), seamlessly blending the sidebar with the content pane.
- Refactor: Renamed unused `_cx` parameter to `cx` in the settings dialog render closure since it is now being utilized to access the theme.
- Implement 4-sided inner absolute border for active pane focus
- Fix 'exit' gracefully closing tabs not removing empty tab groups
- Sync system monitoring automatically on active group switches
