Closes #75.
`bin/entrypoint.sh`, which already runs as root, now makes the data directory usable before the backend starts: it creates `DATA_DIR` if missing, gives it and `/data` to the `netwatch` user (`chown -R`), and sets mode 750 on both, the mode the backend gives a directory it creates. The backend still runs as `netwatch`. The README "Running under upaas" section loses its first-run step that created and chowned the host directory and names only the path to mount. The Dockerfile's build-time `mkdir` and `chown` of `/data` are gone, since the entrypoint now does this on every start.
What the diff does not show:
- The host directory mounted at `/data` ends up owned by uid 1000 with mode 750, and everything under `DATA_DIR` is chowned to uid 1000 on every start.
- If the directory cannot be created or chowned, the container stops with that tool's error before either process starts.
Recorded runs with `--mount type=bind`: an empty directory owned by root (mode 755, and again mode 700), and one holding a `reports` directory and report file owned by uid 1001 with mode 700. Each time the container turned healthy, `netwatch-server` ran as `netwatch`, and a posted report was written to `DATA_DIR`; a second start on the root-owned and the uid 1001 directories did the same.
Judgement call: `/data` itself is given to `netwatch` as well as `DATA_DIR`, so the backend can reach `DATA_DIR` inside a host directory with mode 700.

nginx sent none of the security headers REPO_POLICIES.md requires.
security-headers.conf now sets all six with always, included at server
level and again in /assets/, whose own add_header would otherwise drop
them. nginx hides the copies netwatch-server sets, so /api/ and the
health check carry each header once. The content security policy
allows no inline script or style; the host row's status dot took its
grey from a style attribute, now a class. connect-src is * because
several probed hosts redirect to other hosts and the browser checks
every redirect against it. Referrer-Policy is no-referrer, as the
backend already sends.
Model: opus-5-5
The image's HEALTHCHECK requests /.well-known/healthcheck through
nginx on the port from PORT, so it fails unless both processes answer.
The backend reads PORT and DEBUG with strconv instead of viper, which
turned a bad PORT into 0 and a bad DEBUG into false. Those, and a
BIND_ADDRESS that is not an IP address, now stop the start with an
error naming the variable; the TRUSTED_PROXIES error names it too.
bin/entrypoint.sh also refuses a container PORT outside 1 to 65535,
or 8081, where the backend listens, naming PORT. README.md gains
"Running under upaas". Its first-run steps create the host directory
owned by uid 1000, so the image changes no ownership.
Model: opus-5-5
nginx.conf is now a template the nginx image renders into conf.d at
container start. bin/entrypoint.sh sets PORT to 8080 when unset or
empty, and stops with an error before starting anything when PORT is
not digits only: nginx would take a value such as localhost or
unix:/tmp/x.sock as an address and start anyway. NGINX_ENVSUBST_FILTER
limits the rendering to PORT, so $uri, $host and every other nginx
variable pass through unchanged. server_tokens off drops the version
from the Server header and error pages. script/frontend-viewport-test
renders the template the same way. EXPOSE still documents 8080; the
backend stays on 127.0.0.1:8081.

The root Dockerfile builds the only image; Dockerfile.backend is gone.
Its stages: lint, a Go stage that runs the tests and builds
netwatch-server, the node stage, and an nginx runtime. nginx serves
dist/ on 8080 and proxies /api/ and /.well-known/healthcheck to the
backend on 127.0.0.1:8081. bin/entrypoint.sh starts both, turns TERM or
INT into a stop of both, and exits non-zero when either exits on its
own. The backend runs as user netwatch and keeps reports on the /data
volume. New setting BIND_ADDRESS (empty: every interface). STOPSIGNAL is
SIGTERM, since the nginx image's SIGQUIT would miss the entrypoint.
script/docker is the org model verbatim.

Root make check, and with it the pre-commit hook, now gates the Go
backend too. The backend's Makefile targets are shims over
backend/script/*; script/cibuild builds both images and is the
workflow's only build step. Root make test runs both halves within one
30-second timeout.
Root make lint runs golangci-lint only in Docker, by building the lint
stage of Dockerfile.backend without the cache; the .golangci.yml drift
check moved into backend/script/lint. script/bootstrap installs no
linter: it reuses a Go at least as new as backend/go.mod asks for,
otherwise installs the pinned, hash-verified release, linked into
~/.local/bin without replacing anything it did not create. With VERSION
unset or empty, the backend version falls back to git describe inside a
git checkout, then to dev.

Resolves#11. The frontend/root `Dockerfile` ran only `RUN yarn build`, so `script/lint` and `script/fmt-check` (prettier) never gated CI — only a broken build failed it. (`script/cibuild`'s comment even claimed "the Dockerfile runs make check", which was false.) The backend `Dockerfile.backend` already runs `make check`; nothing covered the frontend's lint/fmt-check.
Change (single file, `Dockerfile`):
- `apk add ... git` -> `apk add ... git make` (build stage needs `make`).
- `RUN yarn build` -> `RUN make check` — which runs `script/test` (`yarn build`, producing `dist/`) then `script/lint` + `script/fmt-check`. `dist/` is still produced in one build (no redundant rebuild); the final nginx runtime image is unchanged.
Verified via a fresh clone (a worktree's `.git` pointer breaks `vite`'s `git rev-parse`, so builds must come from a real checkout — as CI's `actions/checkout` provides): positive `docker build` succeeds with in-image `make check` green; a negative test (a prettier-violating but build-valid file) makes the build fail at `make check`, confirming CI now goes red on a check regression, not just a broken build.
Left open for review (not merged).
