Surface the fetched job metadata (show/episode or movie title, season,
episode, release/airdate, media type) and the source audio/subtitle streams
through the tracker and /status, and render them in the dashboard's current-job
card. Audio channel counts are now probed and shown as 5.1/2.0/etc.
ETA now reads as a wall-clock finish time plus remaining duration, e.g.
"17:49 (3h52m)". Recent events drop the per-row date for a WhatsApp-style
Today/Yesterday/date divider with time-only rows. All dynamic strings are
HTML-escaped, since metadata and filenames are user-controlled.
Stream ffmpeg -progress during the video encode into an in-memory tracker
(internal/status) so the long-running step is no longer a black box: percent,
fps, speed, and ETA are derived from the source duration and updated ~1/s.
Progress prints to stdout only (no logs.db row) to avoid burying real events.
Expose it over HTTP (internal/server, default :8080, set http_addr to "" to
disable): GET /status returns the live snapshot, the pending input queue, and
recent non-debug events; GET / serves an embedded dashboard that polls /status
every second. The server shuts down on the same SIGINT/SIGTERM context as the
watcher.
