Levi Neely 553d2ca0ba Phase 80: eliminate all 43 if(!dpy) return guards via vtable dispatch 
Remove every 'if (!dpy) return' guard from policy files by moving
X11 mechanism code behind WMBackend vtable slots. Call sites now
dispatch through wm_backend->slot(), the X11 backend implements the
mechanism, and the Wayland backend provides no-ops or Wayland-native
implementations.

New vtable slots added to backend.h:
- Frame: frame_alloc_border_pixel, frame_update_texture, frame_paint_button
- NETWM: netwm_init, netwm_cleanup, netwm_update_desktop,
  netwm_get_current_desktop, netwm_update_opacity, netwm_update_actions,
  netwm_check_client_hints, netwm_check_initial_state, netwm_get_pid,
  netwm_cleanup_frame_extents
- Properties: prop_get_protocols, prop_get_check_property,
  prop_set_wmaker_protocols, prop_set_icon_tile, prop_cleanup
- Client: client_restore, client_set_state, client_send_protocol,
  client_kill, client_get_colormap_windows
- Misc: eat_expose, move_window, slide_windows, get_text_selection,
  get_shortcut_string, get_command_for_window
- Icon: icon_update_pixmap, icon_paint
- AppIcon: appicon_show, appicon_paint, appicon_bounce
- Shutdown: restore_desktop, wipe_desktop
- Resources: get_color_for_colormap, free_color, colormap_install
- Protocol: xdnd_init, motif_get_hints
- Startup: manage_all_windows
- Event: event_handle_signal_exit

Structural changes:
- MWMHints moved from motif.c local typedef to motif.h
- WProtocols given struct tag for forward declaration
- Static functions made non-static: wGetTextSelection, wGetCommandForWindow,
  wGetMWMHints, wWipeDesktop, wManageAllWindows, wNETWMUpdateWindowOpacity

Verification: grep -rn 'if (!dpy)' src/*.c returns zero results.
nm wl_backend.o confirms no new X11 symbols in Wayland path.

Levi Neely 803666fd5e WIP: Pure Wayland WINGs screen init (no X11 in WM path) 
- WMCreateScreenWithRContext: add Wayland path that skips all X11 calls
  (no GCs, no atoms, no XListProperties, no XCreateGC)
- screen.c: skip RCreateContext in Wayland mode (pass NULL rcontext)
- Wayland path initializes: font/event/render backends, colors, fonts

Current issue: W_RealizeView tries to create X11 windows for WINGs
widgets. Need to make view realization work without X11 (views should
be pixman buffers in Wayland mode, not X windows).

The grey background + cursor render correctly. Startup reaches
WINGs init but crashes when widgets try to realize without a display.

Levi Neely 9b2448dd7f WIP: Wayland backend - fix atoms, OR surface compositing, frame/window ops 
Key changes in wl_backend.c:
- wl_atom_intern: call XInternAtom on XWayland display (was returning 0)
- Add wl_or_view struct to track override_redirect XWayland surfaces
- handle_xwayland_new_surface: composite OR surfaces via scene graph
- frame_create_toplevel/child: create real X11 windows on XWayland
- frame_destroy/configure: delegate to Xlib
- window_map/unmap/move/resize: fall through to Xlib for frame windows
- stacking_raise/lower: update scene graph + Xlib fallback
- event_flush/sync: call XFlush/XSync on XWayland display
- window_set_border/border_width/clear: delegate to Xlib
- window_get_rect: query XWayland geometry for non-toplevel windows

Note: frame creation via XWayland is a temporary bridge. The correct
architectural approach is native scene-buffer rendering with pixman.
