refactor: simplify Docker setup with public images

- Replace private kurtfm image with official redislabs/redis image
- Simplify docker-compose.yml to essential services only
- Remove Makefile in favor of direct docker-compose commands
- Update Dockerfile to build unified redisctl binary with Rust 1.89
- Remove CLAUDE.md and add to .gitignore
- Update README with simplified Docker instructions
