Script API: expose shulker box item inventory (ItemInventoryComponent)

Bedrock... We built a pack whose only job was to ask a shulker box what's inside. The bundle answered. The shulker didn't. So we're asking you.
1.26.40 with stable @minecraft/server 2.9.0, a held vanilla shulker box returns an empty getComponents() list and no minecraft:inventory. A filled bundle in the same slot, probed by the same code, returns minecraft:inventory with a working container. Item-linked containers are already supported; shulker boxes just don't expose theirs. That makes a proper shulker preview, shulker search, or Ender-Chest shulker management impossible for any Realm-safe add-on; the five-line tooltip is the ceiling. Request: give shulker box ItemStacks an ItemInventoryComponent with a 27-slot Container, read at minimum, read/write ideally, round-tripping through clone()/setItem() and place/break.

P.S. The bundle already talks to scripts. The shulker box is just shy. Help us coax it open.
