UI and widgets

Argui has native Rust UI primitives and TSX adapters for Solid and React. The @argui/widgets package composes those primitives into themed controls. Choose the guide for the layer you are changing:

• Widgets and controls: component inventory, state, and TSX use.
• Custom components and state: compose rectangle, row, column, and text, with two live WebAssembly examples.
• Interaction: native events, focus, text input, and popups.
• Theme: root provider, semantic colors, variants, and overrides.
• Accessibility: names, roles, relations, and actions.
• Layout, scrolling, and animation: geometry and motion used by both the Rust and TSX layers.

The generated public TSX contracts live in packages/solid/src/jsx.generated.ts and packages/react/src/jsx.generated.ts. Widget props live in packages/widgets/src/shared/types.ts and new-controls.ts.
