chore: add project config, Claude instructions, and reference docs

- CLAUDE.md: project guidance for Claude Code (build commands, conventions,
  editing rules, CI notes)
- AGENTS.md: agent-level task conventions for autonomous editing sessions
- .claude/: skills, memory, and settings for Claude Code integration
- docs/: research-backed LaTeX reference examples (small, medium, large-doc
  templates with latexmkrc, local .sty, CI workflow)
