Every proxied request flows through one shared OpenResty location whose
behavior is chosen at request time from the host's Redis hash. Add per-host
controls as new Host fields enforced in Lua rather than static nginx config
(which can't key off a per-request variable):
- Rate limiting: per-client-IP token bucket via resty.limit.req
(ratelimit_enabled/rate/burst), backed by a new `ratelimit` shared dict.
- Response caching: opt-in per host via a global proxy_cache zone gated by
$skip_cache (respcache_enabled). Off by default; upstream Cache-Control
still honored.
- Custom/security headers: req_headers (upstream) + resp_headers (client) and
hsts_enabled, applied in access/header_filter phases.
- IP allow/deny CIDR lists via resty.ipmatcher (deny wins; non-empty allow is
default-deny).
New ops/nginx_conf/hostfeatures.lua holds the enforcement; proxy.conf's
access_by_lua string becomes a block that calls it, plus a header_filter block.
nodejs/utils/host_features.js is the pure, unit-tested normalize/validate layer
(header/CIDR parsing, range clamping, injection-safe values) applied in
routes/host.js and mirrored by the hosts.ejs edit form. install.sh gains the
ipmatcher rock, the cache dir, and the hostfeatures.lua symlink.
Per-host cache TTL is intentionally deferred (global default only) — see the
plan's limitations.

The installer is meant to be run by CI/CD with no human writes on prod, so
updates should mirror the repo exactly rather than refuse on local drift:
- Replace `git pull --ff-only` with fetch + `checkout -B origin/$BRANCH` +
`reset --hard` + `clean -fd` so the box always matches origin/$BRANCH.
- Set GIT_TERMINAL_PROMPT=0 so a missing/expired credential fails fast in CI
instead of hanging on a prompt.
- npm ci --omit=dev (lockfile, production-only) with a plain-install fallback.
- Allow REPO_URL / REPO_DIR / BRANCH to be overridden from the environment.

Rework the installer so it doubles as an updater:
- Idempotent throughout: `install -d` for dirs, apt source lists rewritten
in place, `gpg --dearmor --yes`, fallback cert generated only if missing,
repo cloned or fast-forwarded, and `ln -sfn` symlinks.
- Config is now symlinked straight from the checked-out repo instead of
wget-ing raw files from GitHub. /etc/openresty/{nginx.conf,autossl.conf,
sites-enabled/000-proxy}, the targetinfo.lua lualib, and the systemd unit
all point at $REPO_DIR/ops, so an update is just `git pull` + reload with
no re-copying. This also drops the external t42-common raw-file
dependency (autossl.conf / proxy.conf now come from this repo).
- Validate `openresty -t` before reloading so a bad config can't take the
proxy down; reload if running else restart.
- Fix prior bugs: stray `curl sudo apt-get update`, duplicate openssl cert
line, and `cd ../nodejs` (now cd $REPO_DIR/nodejs). Require root; add a
BRANCH override (default master).
