feat(demos): take over the ten framework-independent samples from Hi.Sample.Wpf

Hi.WinForm and Hi.WpfPlus are being retired, and Hi.Sample.Wpf existed only to demonstrate Hi.WpfPlus -- but ten of its fourteen files never touched WPF at all. Those move here rather than leaving with it: - The three displayees upgrading-to-3.2/breaking-changes.md tells callers to copy -- MachiningProjectDisplayee, IsoCoordinateEntryDisplayee, HeidenhainCoordinateEntryDisplayee. They compose only public API over LocalProjectService, which is the point of shipping them as a starting sample; that doc now points at Hi.Sample/Disp/. - Seven display demos -- Cylindroid, DiscreteRgb, Drawing, Pick1, Pick2, Pickable, Satellite. Their only WPF coupling was the closing DemoUtil.RunApplication call. DemoUtil is rewritten for a project with no canvas. HiAPI ships none any more, so a sample cannot end by opening a window; Present() initializes the app, reports the displayee's type and bounding box, and shuts down, which makes the samples runnable and checkable headlessly and puts the handover where it actually is -- the application assigns the composed IDisplayee to its own canvas' DispEngine. The four files that genuinely need WPF (DemoStl, the old DemoUtil, and the two Machining demos) stay behind and retire with Hi.Sample.Wpf. Each moved file's own [!code-csharp] doc-comment path was repointed from ~/../Hi.Sample.Wpf/Disp/ to ~/../Hi.Sample/Disp/. Builds clean at x64: 0 warnings, 0 errors.
