Average pooling to a fixed 2-D output size, the window derived per output position; the input is channels-last. The module form of [`ClikaRT::ops::adaptive_avg_pool2d`](../ops/adaptive_avg_pool2d.md#adaptive_avg_pool2d), which documents the full contract (shapes, dtypes, errors); construct once, then call it like a function.
