Interface VersionOptions

Where it answers. Default /version, false to serve nothing.

Public on purpose in most deployments: knowing which build answers is what shortens an investigation. Serve nothing when even that is more than you want to say.

What this build is called: a tag, a commit, a release number.

Declared, never guessed from the environment: an application already knows this and already has a place to put what it knows. blueprint.set('stone.telemetry.version.release', …) from a configuration class is the whole setup.
