MajorLinux 8d4dee5da3 troubleshooting: correct ssh tailscale-race article (Fedora ListenAddress variant + playbook cycle landmine)
- Fedora hosts are NOT automatically immune: a leftover manual
  `ListenAddress <tailscale-ip>` drop-in reintroduces the sshd boot bind-race
  even under firewalld (hit on majordiscord 2026-06-07; fix = remove it).
- The Ubuntu playbook kept shipping the cycle-causing [Unit] gate on
  ssh.socket despite the 2026-06-04 resolution; re-running it re-armed the
  ordering cycle (clobbered majorlinux; majortoot-hetzner found armed).
  Corrected in MajorAnsible e0d35aa. Fleet ssh-lockdown state is inconsistent
  (dcaprod/tttpod lack wait-ready; teelia no override) — needs a per-host audit.
