diag(phys): A6.P5 [cellset-build] probe — log BuildCellSetAndPickContaining output

Browse source 
One [cellset-build] line per call when ACDREAM_PROBE_CELLSET=1: seed cell,
sphere world XY, candidate count, full candidate id list. Used to prove
the cellSet for the player's start cell doesn't include the door's outdoor
cell across the over-penetration tick.
