[Feature request] Programatic migration

[nexovec]

Hi,
I'd really like a way to do river migrate-up programatically in go. This would allow me to smoothly react to failing migrations and have more control over the process. There is currently no mention of this in the docs, but maybe it's already possible, since the CLI can do it?

I know I can just fork the process, but that's really ugly.

This was partially motivated by river CLI somehow failing to install

go install github.com/riverqueue/river/cmd/river@latest
# github.com/riverqueue/river
/root/go/pkg/mod/github.com/riverqueue/river@v0.11.3/client.go:481:27: undefined: baseservice.NewArchetype
/root/go/pkg/mod/github.com/riverqueue/river@v0.11.3/client.go:659:30: c.baseStartStop.StoppedUnsafe undefined (type startstop.BaseStartStop has no field or method StoppedUnsafe)
/root/go/pkg/mod/github.com/riverqueue/river@v0.11.3/client.go:720:23: undefined: startstop.StartAll

(Issue #538 )
