fix(tailwind): pseudo selectors

[bukinoshita]

Summary by cubic

Fixes Tailwind rule splitting to treat pseudo-selector utilities (e.g., :hover, :focus) as fully non-inlinable, preventing them from being inlined as base styles.

• Bug Fixes
  • Added pseudo selector detection in splitMixedRule (checks for PseudoClassSelector/PseudoElementSelector) and returns the whole rule as non-inlinable.
  • Added a test to ensure utilities like .btn:hover are not inlined and remain in the non-inlinable set.

^{Written for commit 184a013. Summary will update on new commits.}
