fix: intermitent error during build

[gabrielmfern]

Experimenting with solutions to see if the problem goes away

Summary by cubic

Fixes intermittent build errors by making the Tailwind wrapper version-aware: uses an async setup path for React 19 and keeps useSuspensedPromise for older React. This stabilizes builds and preserves style inlining.

• Bug Fixes
  • Detect React 19 and await setupTailwind in an async component.
  • Fallback to useSuspensedPromise for React <19 with a stable cache key.
  • Extract Inner to share render logic and pass a typed TailwindSetup.
  • Export Tailwind via a version-gated Component for consistent behavior.
