feat: Use our own native DOM types in JSX

[jsantell]

• Extend RenderNode with undefined and Opaque<any>
• Extend CellLike to include OpaqueRefMethods and Opaque
• Added namespace CTDOM, defining valid native DOM elements and attributes, similar to what Preact/React provides. Native events elided.
  • In lieu of a "compiling .d.ts" files solution, or change how we handle implicit types in compiler, this is one big file
• Extend jsx.d.ts with our own Elements.
  • Types were mostly added as-needed. We have a lot of components! Not sure how we want to type some of the events/CellLike values.
• Extend native and CT elements with our own onClick cell-based handler. Can extend more as needed.
• The permissive parameter [elemName: string]: any; has been disabled for now. Can re-enable to allow undefined elements as needed.
• Applies to workspace as well as patterns

Summary by cubic

Defined CTDOM types directly in jsx.d.ts to replace TypeScript’s DOM lib, adding strong typings for native HTML tags and CT custom elements in the sandboxed runtime. Also extended JSX wrappers and RenderNode to support Opaque and undefined.

• New Features

  • Introduced CTDOM with DOM/ARIA typings and a comprehensive native IntrinsicElements mapping.
  • Typed a broader set of CT elements (e.g., ct-screen, ct-button, ct-chat, ct-code-editor, ct-prompt-input, ct-tags, ct-toolbar, ct-vscroll/hscroll, common-* variants) with structured props.
  • Added a cell-based onClick handler in HTMLAttributes; expanded CellLike to include Opaque and OpaqueRefMethods; RenderNode now allows undefined and Opaque.

• Refactors

  • Rewrote jsx.d.ts to use CTDOM and DetailedHTMLProps-based mappings; removed loose prop shapes.

should this always be an array?

[jsantell]

type RenderNode = RenderNode[] | .. so this suffices, I think in the html renderer we make it an array if not

looks great! obviously a lot to eventually carefully trim down, but this will last us for a bit, thank you!
