pickLowestFreeSlot fills gaps before extending (deterministic, compact, predictable for admins reading the controller). Range is a parameter (HeatSync passes 0-200) so it stays adapter-generic. Ignores duplicate/ out-of-range/non-integer used slots; reports slot_exhausted when full. slotCapacity for 'controller full N/N' messaging. 8 unit tests.
