v2.1.5: self-learning ownership — inject queried out-of-catalog defs (Supporter/DLC)

User session traces: only defs 7 & 51 queried all session, both OUTSIDE the
59-id store catalog -> those are DLC-granted items (Supporter flashlights).
Blind 1..256 sweep polluted userItems and broke pet display (reverted v2.1.4).

Now hUserHasItem/hPlayerHasItem remember every def the game asks about into a
global registry; fabricateOwnership() injects any remembered-but-missing id on
its next 15s cycle. Only game-validated ids enter the list — converges to
everything-owned without garbage.
