feat(ui): complete retail cursor state machine

Port every reachable ClientUISystem cursor branch through the production DAT enum map, preserve global-default versus widget-local event ordering, and surface the registered OS fallback. Route all four toolbar stance indicators through the same combat toggle command as the key binding, with golden DAT and transition conformance coverage.

@@ -491,7 +491,7 @@ behavior. Estimated 17–26 days focused work, 3–5 weeks calendar.
 - **☐ D.5.3 — Toolbar selected-object display (issue #141) + exact shortcut preservation.** Wire unified selection to the hidden mana meter (`0x100001A2`), stack entry (`0x100001A3`), stack slider (`0x100001A4`), and complete health/name behavior. Preserve all raw `ShortCutData` fields while keeping `gmToolbarUI` object-only, matching `UpdateFromPlayerDesc @ 0x004BF810`. The eight `favorite_spells_` lists belong to the separate spellbook/spell-bar phase. (Click-to-use + peace/war + health/name already landed.)
 - **☐ D.5.5+ — Core panels.** Inventory (`gmInventoryUI`/`gmBackpackUI`), equipment/paperdoll (`gmPaperDollUI`/`gm3DItemsUI` + the `UiViewport` 3D doll), vendor, trade, spellbook. Research drop done (`docs/research/2026-06-16-*`). Depends on **D.5.4** (data model) + the item-slot/list/icon spine (D.5.1/D.5.2) + the **window manager** (Plan 2: open/close/z-order/persist + faithful grip/dragbar drag-resize) + the drag-drop spine wired (`UiRoot` has the chain; the per-cell accept/drop hooks are still stubs in `UiField`). Also deferred from D.5.1: drag/reorder + the `AddShortcut`/`RemoveShortcut` mutate wire.
 - **D.6 — HUD.** **Radar/compass IMPLEMENTED 2026-07-10; live-world visual gate pending.** It is the retained retail `gmRadarUI` (`LayoutDesc 0x21000074`): a 120×140 circular radar (`0x06004CC1`) with N/E/S/W token sprites orbiting the face, a fixed bright-green player marker, and the coordinate footer (`0x06004CC0`). Projection is `radarPixelRadius / radarRange` with 75 m outdoor / 25 m indoor ranges — there is no 1.18 factor or scrolling compass strip. It lives in `AcDream.App/UI` beside the other imported retail panels. Remaining D.6: target name plate, damage floaters, and other world-space HUD elements through the raw `TextRenderer` path. See slice 06 §A.2, `docs/research/2026-07-10-retail-radar-pseudocode.md`, and the named `gmRadarUI` decomp.
-- **D.7 — Cursor manager.** OS + dat-sourced custom cursors (`FUN_0043c1c0` GDI HCURSOR builder pattern from slice 03). **(D.2b dependency.)**
+- **✓ SHIPPED — D.7 — Cursor manager (user-confirmed 2026-07-11).** All reachable `ClientUISystem::UpdateCursorState @ 0x00564630` branches resolve through production DAT EnumIDMap table 6, with event-ordered global-default versus captured/hovered `MediaDescCursor` layering from `UIElementManager::CheckCursor @ 0x0045ABF0`. OS fallback remains only AP-72 and emits a visible diagnostic. The live gate covered world/object, combat, targeted-use, text, move/resize, and drag contexts; combat-indicator mouse clicks and the quick key share the same toggle command.
 - ~~**D.8 — Sound.**~~ **Superseded — shipped as Phase E.2** (`SoundTable`/`Sound` dat decode, OpenAL 16-voice engine, per-entity 3D positional audio via `AudioHookSink`). Entry kept here for history; see the shipped table.
