+Fix per-channel activation quantization crashing with a shape-mismatch `RuntimeError` on MaxPool/AvgPool/AdaptiveAvgPool layers whose shared observer spans an axis the pool shrinks (e.g. a spatial axis under a stride>1 pool). Axes pooling never touches (batch, channel) keep working as per-channel; only the specific unsafe axis falls back to per-tensor, with a warning explaining why and how to pick a safe axis instead.
