0.1.0

Initial release. A fresh pure-Dart port of KaTeX — no Flutter dependency.

• Pipeline: Lexer → MacroExpander → Parser → parse-node AST → builders → backend-agnostic box tree → SVG.
• Public API: renderToBox(tex, {options}) and renderToSvg(tex, {options}) + KatexOptions.
• CLI: dart run katex_dart "\frac{a}{b}" emits self-contained SVG.
• Coverage: fractions, sub/superscripts (+ primes), roots (+ index), big operators (\sum/\int/\prod/\oint/\bigcup) with limits/nolimits, \left…\right and sized delimiters, accents (incl. stretchy \widehat/\vec/\overrightarrow), fonts (\mathbf/\mathbb/\mathcal/…), colors, sizing/styling, spacing, and environments (matrix/pmatrix/bmatrix/aligned/cases).
• Verified against original KaTeX (pinned 0.17.0): box dimensions match the KaTeX oracle on the full test gallery within tolerance (most exactly).
• Vendored KaTeX fonts (SIL OFL) embedded in SVG output via @font-face.

Stretchy delimiters/accents beyond the Size4 glyph and the full macro set are incremental follow-ups.
