feat(editors): add Claude slash command and refactor config structure

Reorganize Claude configuration into dedicated subdirectory and add
reusable slash command for updating Docker services.

- Create editors/claude/ directory structure
- Move CLAUDE.md and settings.json into claude/
- Add slash commands directory with update-docker-services command
- Update default.nix to link individual files (allows Claude state files)
