With these new per-axis initial states, PatternSimulator must respect the measurement probabilities for measured input nodes. For example, a pattern that initializes an input with Axis.Z and then measures that non-output node in Z should always return the + result (Stim export now emits R then MZ), but the existing M handler still samples every non-output measurement as rng.uniform() < 1 / 2 and then projects the state; half the time it chooses a zero-probability branch, yielding an impossible outcome or zero-norm state. Please sample these measurements from self.state instead of relying on the old 50/50 shortcut.
