Drop the "autoscaler provisions a worker if none is free" phrasing in
favor of the simpler "request comes in and you get a worker; release and
it scales back down."

Serverless autoscaler to spin instances up and down based on demand on
*your* side.
For each batch of work your side wants on a Vast instance, you POST once to
`/reserve`. The autoscaler provisions a worker if none is free; the request
stays open, keeping that worker counted as busy. When your queue consumer
finishes its work it POSTs `/release` on `127.0.0.1:18999` and the held
`/reserve` returns `200`, so the request is recorded as a normal success in
Vast metrics (not a cancellation).
A request comes in and you get a worker. Release and it scales back down.
POST to `/reserve` and serverless gives you a worker, held busy for the
lifetime of the request. When your queue consumer is done, POST to
`/release` on the internal port (`127.0.0.1:18999` by default) and the
held `/reserve` returns `200`.
