Remove internal LAN IP, SSH user, and developer paths from docs and examples; move deploy runbook to gitignored docs/private with a public template; drop Cursor debug logging leftovers; add CI checks to prevent regression.

RustDesk clients could not log in after v3 when handlers moved to Go but
nothing listened on :21121 (API_ENABLED off) or Go bound the wrong port.
Go serves /api/login on 21114; the console proxies legacy :21121 URLs to
Go. Installers repair .env/systemd, Docker publishes both ports, and
firewall rules allow 21114 and 21121 on full installs.
Also includes betterdesk-support-agent (Fyne desktop helper) and
docs/important/ operator notes (API ports, update flow, agent roadmap).
