What

Adds AIComponentBuilders.math, with AIMathProps (tex, style, inline). An AIMarkdownBody with no mathBuilder of its own now asks the nearest AIComponentFactory to render its LaTeX. With neither, it still shows the TeX source, as before.

AIComponentFactory(
  builders: AIComponentBuilders(
    math: (context, props) => Math.tex(
      props.tex,
      textStyle: props.style,
      mathStyle: props.inline ? MathStyle.text : MathStyle.display,
    ),
  ),
  child: AIConversationView(...),
)

Why

AIMarkdownBody only took a math engine through its own mathBuilder, and nothing above StreamingMessageView passed one on. So an AIConversationView's replies couldn't render LaTeX without replacing the whole reply row. A builder fits how code blocks and charts are already customised (AIComponentBuilders.codeBlock, chart). It reaches every markdown body under the factory, with no new parameters threaded through the conversation, its rows or their props. Code highlighting needs nothing new: AIComponentBuilders.codeBlock already covers it in a conversation.

Notes

• A body's own mathBuilder still wins over the factory's.
• Factory-rendered LaTeX is a small widget that reads the builders in its own build, like code fences do. Swapping the builders updates LaTeX already on screen without re-parsing.
• Other platforms: neither the iOS nor the Android AI components render LaTeX today, and neither has a hook for it. This would be Flutter-only.

Testing

• New tests:
  • AIMarkdownBody renders inline and block LaTeX through the factory, and swapping the builders updates it.
  • A body's own mathBuilder wins over the factory's.
  • AIConversationView renders a reply's LaTeX through AIComponentBuilders.math.
  • copyWith and merge carry math.
• dart analyze --fatal-infos is clean.
• The factory, conversation, markdown and streaming-message suites pass with CI=true.
