Detailed Description

TagBox: dense grid of markers (0/1) over a region, input to Berger-Rigoutsos clustering.

Layer: include/pops/amr (AMR geometric primitives). Role: marker structure for cells to refine, produced by tagging and consumed by berger_rigoutsos. Pure integer arithmetic on indices, no physics, no parallelism. Contract: indexed in the index space of its box (lo/hi corners INCLUSIVE, Box2D convention); dense i-fast (j-slow) storage.

Invariants:

a TagBox covers EXACTLY its box; linear indexing assumes i in [lo[0], hi[0]] and j in [lo[1], hi[1]];
markers are 0 (not tagged) or 1 (tagged);
for MPI later, distributed tags will be gathered onto this grid before clustering (clustering is cheap compared to the rest).
