Libation asked GitHub for a newer release every time it started, with no way
to stop it. That is noise for anyone whose install is updated by something
else - a package manager, or an AppImage updater - because the prompt it
raises is one they can do nothing useful with.
Add CheckForUpgradesAtStartup, on by default so nothing changes for people
who rely on the prompt. Only the automatic check is optional: the About
window's "Check for Upgrade" button and the CLI's `version --check` ask for a
check outright, so they run either way. That is why the setting is read in a
new CheckForUpgradeAtStartupAsync rather than inside CheckForUpgradeAsync,
which the startup path and the About button share.
The new setting takes the slot of BetaOptIn, which is deleted here. It was
declared, described and logged, but no axaml or designer ever bound it and
nothing read the value: GetLatestRelease only ever asks for the stable
release, so there was no beta channel for it to select. A stale BetaOptIn key
in an existing Settings.json needs no migration, since PersistentDictionary
ignores keys with no matching property.
Closes#1999

Records every successful audiobook download in the library database (a new
DownloadHistory table) and, when the user opts in, stops downloading once the
rolling 24 hour window is full.
The history lives in the database rather than a file under LibationFiles
because in Docker only the database is on a volume; a file there is discarded
on every container restart.
The limit is checked immediately before each book downloads, never at queueing
time, so a full queue stays full and the user can raise or disable the limit
mid-run. When nothing in the queue can proceed the queue pauses and re-checks
every 15 seconds, recomputing settings, history and clock from scratch, so a
queue left running for days drip-feeds itself as downloads age out. The CLI
never waits: it skips covered titles and reports a count.
