types: the ./catalog export ships no declaration file

[eddyloewen]

Goal

Importing `@webtides/element-library/catalog` type-checks in a strict TypeScript project without a local shim.

Context

The package ships `types/` for the component subpaths, but the `./catalog` export in `package.json` maps only to `./catalog.js`. Under `strict` with `moduleResolution: bundler`, `import catalog from '@webtides/element-library/catalog'` fails with TS7016 (could not find a declaration file). Needed in loewen-digital/sveltekit-ai-starter-template (issue #6 there), which wires the catalog into `@webtides/element-js-ssr-renderer` for SvelteKit; the template carries a `declare module` shim until this lands.

Acceptance criteria

• `import catalog from '@webtides/element-library/catalog'` resolves a typed default export (a `Catalog`: tag → lazy loader) under `strict` and `moduleResolution: bundler`.
• No consumer-side `declare module` needed.

Proposal (non-binding)

Emit `types/catalog.d.ts` from the existing JSDoc (`@type {import("@webtides/element-js-ssr-renderer").Catalog}`) and add `types` to the `./catalog` export condition.

Out of scope

Types for the renderer's own subpaths (webtides/element-js-ssr-renderer#13).
