pointer_query / pointer_query_full: return 1 when compositor is running
(wl_state.started) so the same_screen check in wManageWindow passes and
wSetFocusTo is called for newly mapped XDG toplevels.
Guard frame-dependent calls in the focus update path:
- wWindowFocus (window.c): guard wFrameWindowChangeState on frame!=NULL
- wWindowUnfocus (window.c): same; also guard wFrameWindowPaint on
owner->frame when clearing semi-focus on transient owner

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".
