docs: mark Phase D complete, add src/ audit results

Phase D (WINGs widget X11 elimination) is complete with 7 commits.
The src/ core audit confirms all X11 is already routed through
wm_backend-> dispatch. The entire codebase has zero X11 executing
on the Wayland path.

+### Phase D Summary
+
+| Commit | Files | Description |
+|--------|-------|-------------|
+| 264679a | wwindow.c | ICCCM properties routed through viewBackend vtable |
+| 9eecb25 | wballoon.c, wpopupbutton.c, wtext.c | Drawing routed through render/view backends |
+| 2dce454 | wsplitview.c, wtextfield.c | XOR drawing via xor_fill_rect vtable, removed XRotateBuffers |
+| 9ccfd33 | selection.c | selection_release + selection_request vtable dispatch |
+| 0e26aa8 | wcolorpanel.c | 60 pixmap/copy/fill calls → render backend |
+| 8ec3380 | wcolorpanel.c | Magnifier gated via magnify_callback vtable (X11 provides impl, Wayland NULL) |
+| 7077e00 | wtext.c, wmisc.c | Removed dead X11 code (unused XEvent, dead #ifndef DOUBLE_BUFFER) |
+
+### Verified Safe (no changes needed)
+
+| File | Reason |
+|------|--------|
+| winputmethod.c | W_InitIM called from W_X11PlatformInit only; W_CreateIC/W_DestroyIC guarded by scr->imctx (NULL on Wayland) |
+| wappresource.c | W_InitApplication called from W_X11PlatformInit only |
+| wballoon.c (drawing) | drawBalloon/makePixmap/W_BalloonShowText only reachable via x11_balloon_draw vtable |
+| DnD (dragcommon/dragsource/dragdestination) | drag_begin vtable intercepts WMDragImageFromView; all other DnD code only called from X11 event handlers |
+| wtextfield.c convertSelection | X11 selection handler, only triggered by SelectionRequest X events |
+| wcolorpanel.c magnifier | 40 X11 calls gated behind magnify_callback (NULL on Wayland) |
+
+### Remaining X11 References (compile-time only, no runtime impact)
+
+- `XPoint` struct type in wruler.c, wtabview.c (just 2 ints)
+- `XSetWindowAttributes` in wview.c (struct type for view init)
+- `#include <X11/keysym.h>` for key constants (xkbcommon uses same values)
+- `WMCreatePixmapFromXPixmaps` API name in wbutton.c, wcolorwell.c

 ### D.1 Route `widgets.c` screen init through backends

+- **Phase D complete** (2026-05-23): WINGs widget X11 elimination
+  - All shared widget code has zero X11 executing on Wayland path
+  - 7 commits: wwindow.c vtable (264679a), wballoon/wpopupbutton/wtext (9eecb25), wsplitview/wtextfield xor_fill_rect (2dce454), selection vtable (9ccfd33), wcolorpanel render backend (0e26aa8), magnifier vtable callback (8ec3380), dead code removal (7077e00)
+  - New vtable slots: xor_fill_rect, selection_request, magnify_callback, screen_grab_image (removed)
+  - Verified safe (X11-only paths): winputmethod.c, wappresource.c, DnD, wballoon drawing, wtextfield convertSelection
+  - Bug fix: NULL toplevel crash on Wayland expose dispatch (1ab108f)
+- **src/ core audit complete** (2026-05-23):

+  - wmspec.c → all property access through wm_backend
+  - event.c selection handler → only reached with raw X11 events
