~tw: complete Tailwind implementation in pure SX, split into 3 files

- tw.sx: core engine (HSL color computation, token processor, responsive/
  state prefixes) + visual styles (colors, borders, shadows, ring, opacity,
  transitions, animations, transforms, cursor, decoration)
- tw-layout.sx: spatial arrangement (flex, grid, position, spacing,
  display, sizing, overflow, z-index, aspect-ratio, visibility)
- tw-type.sx: typography (font size/weight/family, line-height, tracking,
  text alignment/transform/wrap, whitespace, word-break, truncate, lists,
  hyphens, font-variant-numeric, antialiasing)

22 color names × infinite shades via HSL computation (not lookup tables).
Full responsive (sm/md/lg/xl/2xl) and state (hover/focus/active/disabled/
first/last/odd/even/visited/checked/before/after) prefix support.
