Probe Q3's body: re-upsert every stored ItemData with its own key in one
commit, through a throwaway scratch console (not part of the repo). Every
record schema-migrated from key 3 (Manufacturer) as an ignored extra slot
after the field's deletion; the rewrite clears that, matching the probe.
115 ItemData records rewritten, 12,686,267 -> 12,683,061 bytes. Reopening
reports 0 ignored-extra-slot migrations across all 180 stored records.
AetherDb factions/dangling/station-fit/loadout-1/hardpoint-fit are byte
identical before and after; census is also identical, because every design's
old Manufacturer field already agreed with the product that sells it (probe
Q1: 0 designs with more than one maker, 0 unset-maker products).
