When a method's `to` state depends on an argument, the hint picks one example argument value and suggests the condition it satisfies, without checking that every value meeting that condition reaches the target state.

Example spec:

```java
@StateRefinement(to = "mode == 2 ? (a(this) || b(this)) : b(this)")
void set(int mode)
```

A later call needing `a(this)` gets the hint "… with mode == 2". After changing the call to `set(2)` the program still fails (the result is only `a || b`), and the same hint comes back.

Expected: suggest an argument condition only when the solver proves the target state holds for all arguments satisfying it; otherwise make no claim.

Found while prototyping the design for #454(b)/#455.
