Support for Tailwindcss version 4.0 & above

[bshital]

Please consider adding support for Tailwind CSS v4+ by:

• Updating parsing logic to handle new utility patterns
• Supporting CSS-driven configuration and tokens
• Ensuring compatibility with modern Tailwind workflows

Current roadmap linkage refresh: issue #19 remains a direct follow-up under #29 (Token interoperability roadmap). The current canonical sequence is #30 (workspace/build reliability) first, then export-surface delivery such as #15 and #19, with #28 after those and #27 as a cross-cutting spec dependency where needed.
