Add missing docs deps to dev, ignore CFFI build artifacts

- Add sphinx-design, sphinxext-opengraph, furo, sphinx-copybutton,
  sphinxcontrib-spelling, linkify-it-py to dev dependencies
- Update sphinx and myst-parser versions for RTD compatibility
- Ignore CFFI-generated C files in src/ directory

Fixes RTD build failure due to missing sphinx_design module.

Note: This work was completed with AI assistance (Claude Code).
