This will allow using it in other places.

By default, builds are not deleted unless they are one year or older. This

Update #30

This was a request from @gdt in #32. Seems reasonable to me!

This was broken by a staticcheck "fix". I had an unnecessary `break`
statement in a case inside a for. As it was, it had no effect since it
breaks out of the `case` but I fixed it incorrectly to break out of the
`for` loop.

Fixes #35

Update #39

This is a preparation for showing the placeholder page once the App Engine instance has been turned down.

Update #39

This branch runs on Go 1.21, not on something ancient.
