test/item/test_inventory.c was disabled via a commented-out
add_subdirectory(item) with no explanation - the actual cause was a stale
"item/inventory.h" include left over from before the rpg/ reorg (real path
is rpg/item/inventory.h). The current inventory.h/.c API it tests hasn't
drifted; only the include path had rotted.
Also fixes a copy-paste bug in test_inventorySort: the "sort by type"
assertions were calling INVENTORY_SORT_BY_ID again instead of
INVENTORY_SORT_BY_TYPE, so inventorySortByType/Reverse had zero real
coverage. Asserts on type grouping only (not the tied FOOD-vs-FOOD order),
since the underlying sort() is qsort and not stable.
