Add GoatCounter analytics, Miniflux, and update CLAUDE.md

- Add self-hosted GoatCounter via systemd binary service (stats.monotrope.au)
- Add Miniflux RSS reader via Docker Compose (reader.monotrope.au)
- Extend Ansible playbook with goatcounter and miniflux tags; all provisioning is idempotent
- Add Caddy reverse proxy blocks for both new services
- Inject GoatCounter script in baseof.html (production builds only)
- Add goatcounter and miniflux Makefile targets
- Rewrite CLAUDE.md to reflect actual project state
