The propose sheet used a free-text seed name, unlinked from the
inventory. Now the seed is picked from your catalogued varieties so the
Plantaré is always tied to a real Variety (tap-through to its detail, and
it shows in that seed's commitments):
- Seed field is an Autocomplete over the inventory; on send the typed name
resolves to the matching Variety, or creates a quick one if it's new —
so varietyId is never null. Sheet takes the VarietyRepository; chat
passes it.
- New repo one-shot `varietyLabels()` (id + label, no joins) feeds the
picker. Deliberately a Future, not `watchInventory()` — a transient
sheet must not hold a live Drift subscription (that hung the widget test
~36 min). Tests use it too and now run in ~2s with bounded pumps + a
tall surface, no pumpAndSettle.
Tests: a new name creates & links a Variety; a matching name links the
existing one without duplicating. ui/services/data plantare suites green.
