v1.8.0
The family list gains guestgraph/connector-apaleo, the first connector: reservations and bookings from Apaleo into the guest graph, built as a client of the engine's API in a repository of its own. The re-sync order places it after the engine, because its specification lives there.
A minor: one vendored file changed, so every member's copy is stale. Taking it: move the release in conventions.json to v1.8.0 and in the uses line of the conventions workflow, run sh conventions/conventions-sync sync, then the member's own suite. Nothing else changes.
