0.5.0

A breaking release: the project is now SweetUI. Every product, module, and command changes name,
and every item declares the 0.5.0 floor. The repository moved to
github.com/mangobyte-dev/sweetui; GitHub redirects the old URL. The website moves to
https://sweetui.dev.

RegistryTheme, registryTheme(_:), registryItem(_:), and every other registry prefixed API
keep their names.

Migrating an app

1. Package: .package(url: "https://github.com/mangobyte-dev/sweetui.git", .upToNextMinor(from: "0.5.0"))
   and .product(name: "SweetUIFoundations", package: "sweetui"), plus
   .product(name: "SweetUIDesignSurface", package: "sweetui") if the app links the design surface.
   In an Xcode project, remove the old package and add the new URL with the same products.

2. Sources: replace SwiftUIRegistry with SweetUI in every import.

3. Receipts: the tool reads only .sweetui/ and rejects a receipt that names another registry. In
   each install destination run:

   mv .swiftui-registry .sweetui
   sed -i '' -e 's/SwiftUIRegistry/SweetUI/g' -e 's/swiftui-ui-registry/sweetui/g' .sweetui/receipt.json

   Step 2 changed each installed file, so info reports it modified; install <item> --update
   merges it back to up-to-date.

4. Theme file: preset apply reads the header // sweetui preset <code>. Rename the old
   // swiftui-registry preset header, or pass --force.

5. Tool: brew uninstall swiftui-registry, then brew install mangobyte-dev/tap/sweetui. Register
   the MCP server as sweetui mcp. The old cache MAY be deleted.
