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.
