- Add utility classes: flex, items_center, font_bold, rounded_lg
- Add enhanced elements: h1/h2/p_styled with styling parameters
- Add simple components: container, card, btn_primary, btn_secondary
- Remove module re-exports from Tailwind (use Tailwind directly)
- Update hello_tailwind example to demonstrate new succinct API
- Add button_demo example showcasing before/after comparison

Reduces ~10 lines of verbose class construction to 1 line:
h1 ~size:\`Xl2 ~weight:\`Bold ~color:(blue 600) [txt "Hello\!"]

- Remove separate V4 module (library is Tailwind v4 only)

• text_shadow, mask, perspective → Effects module
• starting_style → Variants module (convenience function)
- Move accessibility functions to Layout module:
• sr_only, focus_ring → Layout module
- Move tw function from top-level to Css module (better logical organization)
- Update all examples and tests to use Css.tw instead of tw
- Update tailwind-html library to use Tailwind.Css.tw

Breaking change: tw function moved from Tailwind.tw to Css.tw
