Create the two required documentation files for MCNS:
- README.md: project overview, quick-start (build/configure/run), links
to ARCHITECTURE.md and RUNBOOK.md
- RUNBOOK.md: operator-focused procedures with numbered steps covering
health checks, start/stop/restart, backup/restore, log inspection,
and incident playbooks for database corruption, certificate expiry,
MCIAS outage, DNS resolution failures, and port conflicts
