dela 866173a831 Add source linter, negative test fixtures, and fallback guidance
- scripts/lint.py: reject raw rectangles, absolute coordinates, hue-budget
  and callout/group/formula-order violations at the source level
- tests/invalid/ + tests/lint-invalid/: negative fixtures proving the
  package and linter reject bad input; test.sh now runs both directions
- references/fallback.md: degraded path when no LaTeX is available
- tests/group-callout.tex: exercise \stgroup and \stcallout
- agents/openai.yaml: agent config
- Docs and .sty updated to match

% An unclosed \stgroup swallows the rest of the band into its fit list; TeX
% only reports the resulting empty row, which does not point at the cause.
