Amy Jeanes db3f3dd46d models: publish the download speed and derive the eta from it (#2052)
* models: publish the download speed and derive the eta from it

Fills in DownloadProgress.speed (bytes per second, declared with the parallel
downloader). The reporter measures the rate between its 0.5 s reports, smooths
it, and derives the eta from the bytes remaining at that rate instead of
extrapolating elapsed time. Speed is zeroed when a download ends, fails or is
cancelled and for a cached artifact, and copied across artifacts that share a
file like the other progress fields.

The big UI's Models page shows "12.3 MB/s" next to the progress bar and the
mici models panel shows it beside the percentage. Both take the max across a
bundle's artifacts, not the sum, since artifacts sharing a file mirror the same
transfer and only one file is ever in flight.

A stall decays the smoothed speed toward 0 without ever reaching it, so below
0.05 MB/s, which would only display as "0.0 MB/s", it snaps to 0. Both UIs
then show "--.- MB/s" while downloading with no rate (before the first reading
or during a stall) instead of a stuck "0.0 MB/s" or nothing, and the speed
recovers straight to the real rate once data flows again. The snap also keeps
the eta in range: without it a stall of about 25 s drove remaining / speed past
the capnp UInt32 eta, and the capnp error failed the download outright instead
of leaving the stall to the read timeout and retries. A test holds a piece
stalled until the published speed reaches exactly 0, and errors on that
overflow without the snap.

* models: take the speed baseline before the workers start

The reporter took its starting byte count after the piece workers were
submitted, and starting each pool thread lets earlier workers run, so
bytes landed in that gap never counted toward a speed sample. Take the
baseline in _download_file before any worker exists and pass it in.

The test runs every piece inline in submit, so the whole file lands
before the reporter starts; with the late baseline the speed stays 0.
