- ansible.cfg: suppress Python interpreter discovery warning
- ansible/inventory.ini: add ansible_host; server IP is now defined in
one place and read dynamically by run-bootstrap.sh
- group_vars/all/ → directory layout so vault.yml is auto-loaded by Ansible
(previously vault.yml did not match any group name and was silently ignored)
- scripts/run-bootstrap.sh: read server IP from inventory, chmod 600 private
keys automatically, show actual SSH error when root login fails
- scripts/bootstrap-deploy-user.sh: add sudoers.d entry for passwordless sudo
(deploy user has no password so sudo group membership alone was not enough)
- nextcloud: fix Redis healthcheck (CMD-SHELL pipe was unreliable in Alpine,
switched to CMD form with start_period)
- group_vars/all/vars.yml: fix Roundcube image tag (1.6-apache and 1.6 do not
exist; correct tag is 1.6.x-apache)
- docs/runbook.md: expand prerequisites (SSH keys section), add step 1 for
setting the server IP, expand bootstrap step with preflight detail, fix
step numbering
