/**
 * Remove isolated voxels and fill isolated empty voxels within mixed blocks.
 *
 * For each mixed block, computes 6 per-direction occupancy masks (in-block via
 * bit shifts + cross-block via adjacent block lookups), then:
 *   - Remove: keeps only voxels with at least one occupied 6-connected neighbor
 *   - Fill: fills empty voxels where all 6 neighbors are occupied
 *
 * Blocks that become empty or solid as a consequence are handled automatically.
 *
 * @param buffer - BlockMaskBuffer with voxelization results (linear-keyed).
 * @param nbx - Grid block dimension X (used to decode block indices).
 * @param nby - Grid block dimension Y (used to decode block indices).
 * @param nbz - Grid block dimension Z (used for neighbor bounds checks).
 * @returns New BlockMaskBuffer with filtered/filled data.
