Reducer-name string accepted by Float64Column.bin(W, reducer). Built-in scalar reducers ('min', 'max', 'sum',
'mean', 'stdev', 'median', 'count') produce one number per
bin. The percentile family is reached via the 'p${q}'
convention (e.g. 'p95', 'p99.9') where q is in [0, 100] —
runtime check enforces the range. The fused 'minMax' is special:
it returns a two-channel { lo, hi } rather than a single
Float64Array.
