ColorScheme, ColorSchemeRegistry, ColorSchemeSerializer and the Schemes
folder move into the toolkit-neutral library, keeping the OpenNest
namespace, so the Avalonia app can share the built-in palettes, the
scheme files and the recolour-on-open rule.
ColorScheme is now pure colour data with a Version that changes with
any colour. Its GDI+ pens and brushes move to GdiSchemeTools in the
WinForms project (still one set per thread, rebuilt after a colour
change), reached through scheme.Gdi(). The legacy part outline uses
ColorShade.Dark, a port of ControlPaint.Dark's HLS arithmetic; a
WinForms test compares the two across a colour sweep on Windows.
The registry no longer walks Application.OpenForms: Apply raises
Applied, and EditNestForm subscribes once to recolour every open nest
window as before. The saved scheme is read under the same
ActiveColorScheme setting (SavedSchemeName/ApplySaved for the shared
user-settings file); WinForms still reads it through Settings.Default.
Schemes/*.json now copies beside both desktop apps from OpenNest.Desktop.
Pure scheme tests move to OpenNest.Desktop.Tests, with new ones for
built-in round trips, scheme files, bad files, the saved name and the
recolour rule.

Add OpenNest.Desktop (net8.0), the toolkit-neutral layer the WinForms app
and OpenNest.Avalonia will share, and OpenNest.Desktop.Tests with a guard
that the library references no WinForms/WindowsDesktop, System.Drawing.Common
or Avalonia assembly, project setting or (transitive) package.
Both desktop front ends reference it; OpenNest.Avalonia joins OpenNest.sln
and the new tests join the Linux CI matrix. No code moves yet.
