The previous version was in Dutch and hardcoded internal deploy details
(hostname alias, personal local path, private Gitea mirror domain) that
had no business being in a public repo. Replaced with a generic version
using <docker-host> placeholders; the internal nc01-specific copy now
lives at notes/deploy-nc01.md, which is gitignored and stays local-only.
Not rewriting prior history for this (confirmed with user: nothing
credential-level was exposed, just a hostname alias and a path).
Was untracked locally and stale (referenced apps/ instead of custom_apps/,
git clone inside the container instead of our tar-based deploy). Documents
the two things that just caused a production incident on nc01: files
extracted from a tarball keep the source uid/gid and need an explicit
chown to www-data, and skipping the installed_version sync after bumping
<version> puts the whole instance in "needs upgrade" state, which blocks
not just occ commands but the web login page too.
Link it from README.md's install section.
