feat(critters): improve animation parsing and font preloading

[riceharvest]

Identified during v2.0.0 audit:

• Improve animation declaration parsing in runtime.js to extract specific names rather than using lazy matching.
• Enhance font parsing to generate multiple type-specific preloads (e.g., font/woff2).
• Verify if certain properties in dom.js are required for css-select integration.
