For anyone who turns DeadAir on, a background task makes each episode a
copy with every silence quieter than -38 dB for over 0.35 s shortened to
0.2 s. Nothing is re-encoded: ffmpeg copies the original's frames and
leaves the silent ones out, about 11 s for an hour of MP3 in a release
build. On Brad & Will's episode 359 that is 520 cuts and 3.3 minutes
saved, the copy decodes clean, and it has no isolated spikes in its
silences that the original lacks.
Cuts are made from the middle of each silence, keeping 0.1 s at each
end, so the frames either side of a cut are silent: decoding blends a
frame with the one before it, and an MP3 frame can begin in the bytes of
the frame before, so the first frame after a cut decodes against the
wrong neighbour. Inside a silence nobody hears that; at a word they would.
Positions stay in the original's time and the server converts them both
ways. The iOS and Android apps save positions themselves from their own
player, even while the page is asleep, so converting in the page would
have stored the copy's times as the original's. /media/{id}/deadair
serves the copy at its own address and records that this person is
playing it; a position saved meanwhile is converted from the copy's
clock, as is the length a player measures.
The copy is made by a task of its own, not the worker: a first pass over
a library is hours of ffmpeg, and scans must not wait behind it. It
checks every two minutes, which covers new downloads, files already
downloaded, a switch turned on and a file downloaded again with one rule.
Episodes everyone who would hear the copy has finished get none.
download::remove deletes a copy with its original, and the quota counts
copies.
Settings: the switch is PATCH /api/me {deadair}, a feed kept out is
PATCH /api/feeds/{id} {deadair: false}. GET /api/me gives the switch and
deadair_saved, the seconds saved on episodes heard 75% or more on a copy,
each counted once. Three new tables, so no ALTER.
The image gains Debian's ffmpeg, about 480 MB, in a layer that stays
cached until the base image changes. The player's switch, the feed
setting and the stat come next, after mockups.

- web/src/*.ts: the script that was inline in index.html and login.html, split along its
existing sections. Still one scope, concatenated in order, not modules.
- web/build.mjs strips the types, puts the script in the page and minifies it with swc;
build.rs runs it into OUT_DIR and web.rs include_str!s the result. 137 KB -> 106 KB.
- npx tsc -p . type-checks web/src, loosely; the handful of annotations it needed
change no behaviour.
- The Docker build installs node and swc (npm ci --omit=dev).
- Two list requests racing no longer let the older one win, and switching tabs clears
the selection it closes, which made a browser test flaky.
Closes#23, #24.

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.
