feat: add DOM shim and style/template generation utilities

- Introduced a minimal DOM shim in `dom-shim.ts` to support FAST Element's `css` and `html` tagged templates in Node.js.
- Added `generate-stylesheets.ts` for converting compiled FAST ElementStyles JS modules into plain CSS files.
- Implemented `generate-templates.ts` to convert compiled FAST Element ViewTemplate JS modules into declarative `<f-template>` HTML files.
- Updated `index.ts` to export new utilities and types for style and template generation.
- Removed unused asset reading functions from `assets.ts` and refactored SSR rendering logic in `render.ts` to utilize the new generation utilities.
