Detailed Description

THE ghost-projection experiment: staggered Zick & Homsy drag, cut-cell vs directional
ghost-cell projection (set_ghost_projection). Success = ghost-mode order ~2 with K converging to
the same Z&H limit; also logs BiCGStab vs PCG iteration counts (solver health / compatibility
floor). Pattern: tests/study/collocated_zh_ab.py.
