CSS-standard layout and rendering

This release makes core layout and rendering behavior more predictable for CSS-like document generation.

Added

• hstack({ wrap: true }) with greedy row wrapping and per-row justification.
• minHeight and maxHeight stack sizing.
• alignSelf across flex items, including text, paragraphs, spacers, lines, images, links, and SVG paths.
• letterSpacing for text and paragraph runs.
• opacity for text and stack rendering.

Fixed

• letterSpacing now participates in measurement, wrapping, hard-breaking, ellipsizing, alignment, and decoration widths instead of only affecting drawn glyphs.
• Stack opacity now propagates to backgrounds, borders, background images, images, SVG paths, text, and text decorations.
• Text opacity now applies consistently to underline and strikethrough decorations.
• Wrapped hstack rows now justify against the full row width.
• maxHeight now constrains vertical shrink layout instead of only clamping the final reported height.
• minHeight/maxHeight clamp order follows CSS: max first, then min wins if they conflict.

Validation

• pnpm run typecheck
• pnpm test
• pnpm run build
