v2 source realm

Package probe is a deliberately trivial realm whose only purpose is to answer one question: does a NEW package submitted to onyx today get enabled by the package approver, or does it park?

Submitted 2026-10-19 after gno.land said the Friday chain upgrade probably had the approver off at the moment garden/v6 was submitted (2026-10-16 16:15 UTC, the same day). probe/v1 was submitted on 2026-10-16 and parked, so this is the same experiment on a day the approver may be back. Nothing in the project depends on this realm.
