enhance: Add version to Queue Item

[cognifloyd]

Description

Add a version field or a versioned envelope to the queue Item.

Value

If a build gets queued and then the server+worker shut down for an upgrade (or a downgrade), then that build is "stale". The worker needs a way to handle this stale data gracefully. The worker should be able to reliably reject any queued items that it cannot handle (for example by failing the build).

Both of these proposals involve changing the queue Item or the underlying executable pipeline.Build. So,

• feat(proposal): Build init Log instead of magic "init" Step #789
• proposal: remove executable pipeline build from the queue #805

Definition of Done

The queue Item has something that allows the worker to reject or fail the build if it cannot handle the version mismatch.
