cleanup: remove Docker, Ansible, and deployment infrastructure

Removes unused deployment and packaging infrastructure:
- Dockerfile and docker-compose.yml (Docker deployment not used)
- ansible/ directory (playbooks, inventory, config)
- packages/@ansible/example/ (npm package for Ansible example)
- docs/deployment/ansible-package-deploy.md
- docs/plans/2026-04-24-002-fix-docker-compose-scheduler-plan.md (obsolete)
- .github/workflows/publish-ansible-example.yml
- .github/workflows/ci-node-packages.yml (only tested packages/)

Updates:
- README.md: remove Deployment section
- docs/plans/2026-04-24-ROADMAP-stemwijzer-improvements.md: mark P1-002 as removed, update sprint 1
