Add a single quickstart table covering Cloudflare DDNS, Usenet, NZBgeek,
WireGuard, stack .env, and bootstrap; point secrets/.env.example and
AGENTS.md at the same workflow.
Expand .env.example with ports, AI, Usenet, WireGuard, demo logins, and
bootstrap flags. One script creates dirs, downloads the model, starts
compose, heals gluetun, and configures SABnzbd from the same file.
Prefer stack_deploy_method=git: init/fetch on the server, register an
SSH deploy key with Forgejo, and leave local secrets untracked. Document
git pull for day-to-day updates; keep rsync as an opt-in fallback.
