Remove setup runbook references from prod roadmap docs so roadmap remains design intent only. Keep setup-to-roadmap links, but normalize them to explicit relative paths.
- Anglicized setup and facts markdown file names for better consistency.
- Updated 01-swarm-init-multinode.md to highlight Ansible automation of Swarm initialization and labeling.
- Overhauled 03-infra-stack-changes.md to describe the single monolithic file strategy and reflect current Redis, RabbitMQ, and etcd cluster configurations.
- Fixed minor overrides and typos in Patroni templates and Ansible bootstrap documents.
- Restructured README and roadmap mapping to align with the renamed setup documents.
