text:
The `determineState` function now:
1. Builds a set from the states slice (order-independent)
2. Checks for states in the priority order from the original switch: `allocated → reserved → idle → down → mixed`
3. Naturally handles the idle+down exception — since `idle` is checked before `down`, it always wins when both are present
