Rename CLAUDE.md -> AGENTS.md (cross-vendor standard) with a relative CLAUDE.md symlink so Claude Code still loads it. Move each .claude/rules file into docs/guides/ (paths: frontmatter preserved) and replace the rules file with a relative symlink into the guide. Repoint the AGENTS.md index paragraph at docs/guides/ so non-Claude agents find the guides.
