phase 1: copy Kindred-only files onto upstream/main (FreeCAD 1.2.0-dev)

Wholesale copy of all Kindred Create additions that don't conflict with
upstream FreeCAD code:

- kindred-icons/ (1444 Catppuccin Mocha SVG icon overrides)
- src/Mod/Create/ (Kindred Create workbench)
- src/Gui/ Kindred source files (FileOrigin, OriginManager,
  OriginSelectorWidget, CommandOrigin, BreadcrumbToolBar, EditingContext)
- src/Gui/Icons/ (Kindred branding and silo icons)
- src/Gui/PreferencePacks/KindredCreate/
- src/Gui/Stylesheets/ (KindredCreate.qss, images_dark-light/)
- package/ (rattler-build recipe)
- docs/ (architecture, guides, specifications)
- .gitea/ (CI workflows, issue templates)
- mods/silo, mods/ztools submodules
- .gitmodules (Kindred submodule URLs)
- resources/ (kindred-create.desktop, kindred-create.xml)
- banner-logo-light.png, CONTRIBUTING.md
