Show the mouse cursor widgets ask for - #594

The OpenGL controller never carried ImGui's requested cursor to the window, so every resize, hand and text-beam cursor was dropped. PlatformCursor now applies it after each frame, the backend advertises HasMouseCursors, and the custom widgets that lacked one set a hand on click targets and resize or move cursors on drag targets. The headless harness exposes the frame's cursor so the widget suites assert each one.

Before: the pointer was an arrow everywhere in an ImGuiApp window. Splitters, window edges, text fields and every custom widget showed the same arrow, even where ImGui or Hexa had already asked for a resize or text cursor.
After: the pointer changes with what a press will do. Text fields show a beam, splitters and window edges show resize arrows, click targets such as switches, chips, segments, stars, piano keys, step cells and page dots show a hand, and drag targets show a resize or move cursor (range slider, handle track, fader, knob, XY pad, colour wheel, curve points, canvas panning).
The root cause was in
ImGui.App, not the widgets: Dear ImGui only records the cursor a frame wants, and the OpenGL controller never passed it on to the window.How: a new
PlatformCursormapsImGui.GetMouseCursor()onto Silk.NET'sICursorafter each frame, writing only on change, and leaves alone a pointer the app has captured or hidden,NoMouseCursorChange, andMouseDrawCursor. The controller now declaresImGuiBackendFlags.HasMouseCursors, which also turns on ImGui's resize-from-window-edges. InImGui.Widgets, a smallWidgetCursor.OnLastItemhelper sets the cursor on the widgets that lacked one. Plain buttons, includingToolbarButton, keep the arrow, as ImGui's own buttons do, and so do read-only or click-less instances. The headless harness declares the same flag and exposesImGuiAppHarness.MouseCursor, so each widget's cursor is asserted in its isolation suite (25 new UI tests), with unit tests for the mapping. CLAUDE.md and the App README describe the policy.Every test project passes locally in Release.
