Add a log view, and Docker packaging

The Log button shows the running daemon live: feed scans, downloads,
torrents and every HTTP request. It reads a ring buffer filled by a
tracing layer rather than tailing a file, so it works under Docker where
logs go to stdout. The access-log middleware skips /api/logs, or the
panel's poll would log itself forever.

Detached torrents could leave a row stuck in 'downloading' across a
restart, where nothing would ever revisit it; those are requeued at
startup.

Dockerfile, entrypoint and compose: 114 MB runtime, config bound to
0.0.0.0 on first run since container loopback is unreachable, drops to
PUID:PGID for Unraid, and a healthcheck that goes through the control
socket so a wedged worker reads as unhealthy.

+## 2026-09-10 — Log view in the app, and Docker
+
+**Log view.** A ring buffer (2000 lines) fed by a `tracing` layer, exposed at `/api/logs` with a
+sequence cursor so the UI polls for "everything after N" without duplicates. Tailing a file was the
+obvious approach and the wrong one: under Docker the logs go to stdout and there is no file. An
+`access_log` middleware adds a line per HTTP request, so the daemon and the web side share one
+stream — which is what Ray asked for. That middleware skips `/api/logs` itself, or the panel's
+2-second poll would generate a line per poll forever, a log of nothing but its own requests.
+
+UI: sidebar **Log** button, level and text filters, follow-tail toggle, copy button, colour-coded
+levels.
+
+**Restart safety.** Detached torrents introduced a `downloading` state, and a row left in it by a
+restart would sit there forever — the pending queue skips it and nothing else revisits it.
+`requeue_interrupted()` resets those at startup, leaving alone any row that already has a file.
+
+**Docker.** Multi-stage build (deps cached separately from source), `debian:bookworm-slim` runtime,
+114 MB. Entrypoint writes a starter config bound to `0.0.0.0` on first run, because a container's
+loopback is unreachable from outside, and drops to `PUID:PGID` via gosu. Healthcheck is
+`ipx status`, which goes through the control socket to the worker and so catches a *wedged* daemon,
+not just a dead one.
+
+Built and actually run, not just written: image builds, container starts, writes its config, serves
+the UI (401 without a token, 200 with), `/api/logs` answers, and the process runs as
+`uid=99(ipx) gid=100(users)` with files owned `99:100` and the token file at mode 600.
+
+Worth noting for future testing here: this session's Docker socket belongs to the Unraid host, so
+`-v /tmp/...:/config` binds a path on the *host*, not one visible from inside this container. The
+mount looks empty from here while being perfectly correct — verify inside the container instead.

 ## 2026-09-10 — Torrents: they work, and one was freezing the whole daemon

 clear — and a feed URL can itself contain a credential (Patreon's, for one, carries an auth token).
 Put it behind a reverse proxy with TLS if that matters to you.
 
+## Log view
+
+The **Log** button in the sidebar shows the running daemon's output live: feed scans, downloads,
+torrent activity and every HTTP request, with level and text filters and a copy button. It reads a
+2000-line ring buffer held inside the process (`/api/logs`), not a file — so it works the same under
+Docker, where logs go to stdout and there is no file to tail. `IPX_LOG=ipx=debug` adds detail;
+`IPX_LOG=ipx=info,librqbit=info` shows what torrents are doing.
+
+## Docker
+
+```sh
+docker compose up -d          # builds the image and starts it
+docker compose logs -f ipx    # the token is printed on first start
+```
+
+`docker-compose.yml` mounts `./config`, `./data` and a downloads directory, publishes 8099 for the
+UI and 6881 (TCP **and** UDP — DHT needs the UDP side), and sets `PUID`/`PGID` to `99:100` so files
+land owned the way Unraid shares expect. On first start the entrypoint writes a config bound to
+`0.0.0.0`, since a container's loopback is not reachable from outside it, and prints the URL with
+its generated token.
+
+The healthcheck runs `ipx status`, which goes through the control socket to the command worker — so
+it catches a daemon that is alive but wedged, not merely one that has died.
