Eric Traut 639d2478cc Render aligned equations and optimization notation in TUI math (#47191) ...

## Why

Aligned equations and common optimization notation previously fell back to TeX source. Scripts without Unicode equivalents also prevented otherwise supported expressions from rendering.

## What changed

- Add display layouts for `aligned` and `\boxed`, preserving fraction geometry and alignment with surrounding math.
- Stack sum limits and `\underset`/`\overset` annotations in display math, with compact forms for inline math and nested arguments.
- Support `\substack`, uppercase `\mathcal`, and single-grapheme `\widehat`.
- Preserve scripts without Unicode equivalents using explicit grouping, such as `x_{gpt}` and `x^{q+1}`.
- Keep layouts bounded and retain source fallback for unsupported input or expressions that do not fit.

## Testing

Add snapshots and regression tests for optimization models, display limits, grouped scripts, fraction alignment, narrow-width fallback, malformed input, and layout bounds. Add streaming coverage comparing character-by-character output with complete rendering at wide and narrow widths in rich and raw modes.
