feat(app): ask 'how did it do?' when a harvest is noted (schema v13)

The note growers most wish they had two seasons later — did it do well,
was it worth keeping — never had a home. New append-only GardenOutcomes
table (lotId, season year, three-face rating, free note); the question
appears ONCE, inline, right after recording a harvest in the batch story,
and is skippable without a trace. The answer shows as one more story
line. Rides backups/sync like every mutable table (JSON codec, LWW
import, HLC clock absorb). Migration v12→v13 guarded + verified from
every historical version.
