Guard the remaining wwin->frame dereferences that are reachable for
Wayland windows:
- wSetFocusTo: skip ChangeStackingLevel for fullscreen if !frame
- set_window_coords: fall back to client size when frame is NULL
(called by find_Maximus_geometry on neighbour windows)
- wFullscreenMonitorsWindow: early return if !frame
- wMakeWindowVisible: skip wRaiseFrame if !frame

Add if (!wwin->frame) return guards to wShadeWindow, wUnshadeWindow,
wMaximizeWindow, wUnmaximizeWindow, wFullscreenWindow, wIconifyWindow,
and wDeiconifyWindow so that Wayland-managed windows (frame==NULL) do
not crash when these actions are triggered via menu or keyboard shortcut.

Guard all dpy==NULL / frame==NULL crash sites in the unmanage path:
- wUnmanageWindow (window.c): frame ptr set to NULL-safe expression;
window_unmap, raise_delay timer, and owner border change all
guarded on frame != NULL
- wSelectWindow (actions.c): early return if !wwin->frame
- wNETCleanupFrameExtents (wmspec.c): early return if !dpy
- wClientRestore (client.c): early return if !dpy
Wire handle_toplevel_unmap → context_find → wUnmanageWindow(destroyed=True)
so XDG toplevels are removed from scr->focused_window on client disconnect.
Smoke test: add Phase 40 check — grep "toplevel unmapped".
