A shown item tooltip whose line waited on a cache kept missing that line until something re-ran `OnEnter`. Examples are a lock's key, a "made by" name and a set member. Bags re-run it every frame; trade slots, `ItemRefTooltip` and addon tooltips never do.
1.12.1 registers `CGTooltip::OnCacheAnswer` (`0x52e530`) on every record, name, petition and item-name miss, with the tooltip as cookie. On each answer it rebuilds from the inputs the last build kept (`0x52b6cc`–`0x52b70a`), reading the live object, and sizes the plate (`0x52e5ac`). A clear zeroes the kept entry (`0x5300dd`), so a cleared tooltip stays down.
Every item `Set*` now goes through one build that keeps its inputs and records its misses. Each answer rebuilds whatever the tooltip keeps by then; compare asks stack and builder asks deduplicate, as in the reference.
Tests cover each cache and a cleared tooltip.
