- This allows it to integrate directly into nemo's preferences. We give its own tab now, not shared with extensions.
- The existing python version becomes a wrapper around this, via introspection.
- This lets us integrate directly into cinnamon's Action settings as well.

Pull request overview
This pull request ports the Nemo action layout editor from Python to C and makes it accessible via GObject introspection. The changes enable direct integration into Nemo's preferences dialog with its own dedicated tab, while the Python version becomes a wrapper around the new C implementation.
Key Changes:
- Ported action layout editor from Python to C with GObject introspection support
- Integrated editor directly into Nemo preferences with dedicated "Actions" tab
- Separated Extensions and Actions into distinct preference tabs
- Removed standalone plugin manager in favor of individual config widgets

Making the preferences dialog modal may be problematic without a proper parent window. This can block interaction with the entire application unexpectedly. Consider whether this should be modal, especially given that the parent window is now being passed as NULL in the code.

The scrolled window containing the treeview has can-focus set to False, which may prevent keyboard navigation from working properly. The scrolled window should typically be focusable to allow keyboard scrolling.

Setting the button box to homogeneous will make all buttons (Save, Cancel changes, Default layout) the same width, which may look odd when the button labels have significantly different lengths. Consider using natural sizing instead.

The FIXME comment indicates this string is bad for translation. The issue is likely the embedded markup and newlines. Consider splitting this into separate translatable strings or using g_markup_printf_escaped with a cleaner format string.

The quit() method returns True after calling Gtk.main_quit(), but this return value is meaningless since the main loop will exit. The return statement should likely be removed or changed to return False/None.
