Flutter's globalPosition is window-relative, not screen-absolute.
Now using gdk_device_get_position() on the native side to get
the actual screen coordinates at the moment startDrag/startResize
is called. Dart no longer passes coordinates — the native handler
queries the pointer directly.

Replace XWayland fallback with proper xdg-decoration protocol
negotiation. On Wayland: binds zxdg_decoration_manager_v1 from
the compositor registry, requests CLIENT_SIDE mode on the toplevel
surface — KWin respects this and drops server-side decorations.
Falls back to gdk_window_set_decorations(0) + set_decorated(FALSE)
on X11. GDK_BACKEND=x11 removed from Makefile.
Also fixes mouse-jumping glitch: startDrag and startResize now
pass screen coordinates from Flutter's globalPosition through the
method channel to gtk_window_begin_move/resize_drag.

Without OS decorations there are no resize handles. Added 6px
edge and 12px corner invisible hit zones around the window
perimeter via ClideResizeBorder. Each zone changes the cursor
and calls gtk_window_begin_resize_drag via the clide/window
method channel with a GdkWindowEdge direction.

Hide GTK title bar via gtk_window_set_decorated(FALSE). Add
MethodChannel('clide/window') for drag/minimize/maximize/close
wired to GTK window functions. Dart WindowControls service wraps
the channel. Three per-column hats in RootLayout: left (macOS
traffic lights or plain drag), center (project > branch label),
right (minimize/maximize/close glyph buttons on Linux). Resolves
Q-006.
