Implement CSS Module Scripts (https://web.dev/articles/css-module-scripts)
for Bun's bundler. When importing CSS with `{ type: 'css' }` attribute:
```javascript
import sheet from './styles.css' with { type: 'css' };
// or dynamically:
const module = await import('./styles.css', { with: { type: 'css' } });
```
The import now returns a CSSStyleSheet object that can be used with
`document.adoptedStyleSheets`, instead of the previous behavior of
returning an empty object or file path.
Changes:
- Add `__cssModuleScript` runtime helper that creates CSSStyleSheet
- Add `is_css_module_script` flag to ImportRecord
- Track CSS Module Script files in LinkerGraph
- Generate `__cssModuleScript(cssContent)` for CSS imports with type assertion
- Handle both static and dynamic imports correctly
- Preserve existing CSS Modules behavior (class name mappings) for
imports without the type assertion
