- daily claim: record the claim before granting boosters, so a crash
mid-claim forfeits at most one reward instead of allowing a re-claim
(booster farming) on next launch.
- game screen: disarm the booster target synchronously before awaiting,
so a rapid second board tap can't double-fire a use or stack a dialog.
- new players: seed one of each booster once (idempotent persisted flag),
fulfilling the spec's starting inventory. Wired in main().
