feat(icons): implement shared SVG icon system across packages

- Create centralized SVG files in core icons package assets directory
- Add rollup-plugin-string to core icons for SVG file processing
- Export SVG_ICONS object from core package for cross-package sharing
- Refactor html-icons to import SVG strings from @vjs-10/icons
- Remove hardcoded SVG strings in favor of shared definitions
- Add TypeScript declarations for SVG imports

This establishes a foundation for sharing more code across the monorepo
while maintaining proper package boundaries and build system integration.
