Tight axis-aligned bounding box of a mask's foreground, in voxel indices.
Returns `(z0, y0, x0, z1, y1, x1)` with exclusive upper bounds, i.e.
`vol[z0:z1, y0:y1, x0:x1]` is the smallest sub-volume containing every
foreground voxel. *margin* (an int `>= 0`) grows the box by that many
voxels per side, clipped to the volume — headroom for operators with a
spatial footprint (a Gaussian of sigma s needs ~`3*s` voxels of context).
A non-`{0, 1} input is thresholded at > 0.5`.
An empty mask raises `ValueError` (fail-closed): there is no box, and
silently returning the full volume would defeat the point of cropping.
