fix: comma-separated declaration values parsed as Raw nodes (#101)

* Initial plan

* Fix comma-separated declaration values parsed as Raw nodes

- Import Comma and LeftCurlyBracket tokens in DeclarationList.js
- Fix isElementSelectorStart() to properly handle comma-separated values
- Use positive check for LeftCurlyBracket instead of negative exclusion
- Ensure pseudo-class detection only returns true when followed by {
- Add test cases for comma-separated declaration values

Fixes regression introduced in v3.6.7 where properties like background-attachment,
font-family, and transition with comma-separated values were incorrectly parsed
as Raw nodes instead of Declaration nodes.
