Add base Docker Compose projects under platform-infra/stacks, using the
Phase 1 ZFS platform datasets and shared networks:
- bootstrap-networks.sh: idempotent creation of shared `proxy` (edge) and
`platform` (internal) Docker networks.
- traefik: edge router with TLS/ACME (HTTP-01), global HTTP->HTTPS redirect,
file-based security-headers/TLS middlewares, and a basic-auth dashboard.
Docker access via a least-privilege tecnativa/docker-socket-proxy instead
of mounting docker.sock directly.
- mariadb: shared instance on tank/platform/mariadb, utf8mb4, tuned; not
published to the host (internal `platform` network only).
- forgejo: Git + container registry over HTTPS (SSH disabled to avoid extra
inbound ports), SQLite backend, data on tank/platform/forgejo.
Each stack ships a committed .env.example (real .env is git-ignored) and the
stacks README documents bring-up order, secrets, and verification.
Also add root CLAUDE.md so fresh sessions orient from files cheaply:
philosophy, doc pointers, naming quick-ref, repo map, commands, agreements.
