v2 overhaul

[colinc86]

New Features

• ♿ Accessibility — VoiceOver support via MathJax's Speech Rule Engine (SRE) with .imageAccessibility() modifier
• 🌐 Script Scaling — CJK and non-Latin script support with .script(.cjk) for proper equation sizing
• 📐 Line Spacing — Automatic normalization for inline equations on iOS 18+ / macOS 15+ via custom TextRenderer
• 📊 Arrays & Tables — SVG stroke patching for array, matrix, pmatrix, vmatrix, cases borders and \hline rules
• 🧩 Generic Environments — Any \begin{...}...\end{...} environment (align, gather, cases, etc.) now works standalone without wrapping in $$
• 🖼️ Render to Image — New LaTeX.renderToImages() API returns [UIImage]/[NSImage] for use outside SwiftUI (UIKit, image export, PDFs)
• 📏 Dynamic Type — Equations automatically scale with system text size / accessibility settings
• 🔲 Redacted Placeholder — New .redactedOriginal async rendering style
