Consolidate TypeScript utilities for cleaner imports

- Merge latexUtils.ts + utils/latexParser.ts → utils/latex.ts
- Merge colorUtils.ts into colorSchemes.ts (single getTermColor)
- Move export-only utils (escape.ts, htmlConverter.ts) into export/
- Merge types.ts into export/index.ts (inline ColorScheme, ExportFormat)
- Delete 5 small files, cleaner import paths

Before: 7 utility files scattered across src/ and utils/
After: 3 logical groups (utils/latex, utils/colorSchemes, export/*)
