docs(ops): fix runbook/hotfix/troubleshooting against reality + redact committed sudo password

- operations-runbook: redact the plaintext sudo password (rotate it — it
  stays in git history); replace the nonexistent test-cross-node.sh /
  test-reboot-survival.sh with the real entry points (lifecycle gate,
  multinode smoke, e2e/post-install scripts)
- hotfix-process: de-hardcode the v1.0.x framing, point releases at
  create-release.sh + primary Gitea, correct the rollback backup paths
  (/opt/archipelago/rollback + updater backup dir, not /usr/local/bin)
- troubleshooting: connectivity probe start9.com -> debian.org
- INSTALL.sh: drop removed endurain app, point at developer-guide.md
  (development-setup.md never existed)
- tests/lifecycle/TESTING.md: replace the stale 2026-06-21 mid-session
  resume block with a resolved note; release-gate item 8 reflects the
  2026-07-08 version decision (1.8.0-alpha)
