Ground-stepOffset analogue for climbing (wallStepOffset, default 0.1):
when climb movement is blocked by a small ledge, the capsule lifts
along the wall normal in pre-swept sub-steps and continues, with a
short servo hold to prevent being pulled back into the ledge. Ground
detach while climbing down now requires floor that extends away from
the wall, so narrow step tops no longer cause a mid-wall exit.
Wall->ceiling handoff additionally checks OverheadIsPassableStep():
if the overhead surface is only a small protrusion within the step
allowance, the handoff is skipped and the step pass carries the
capsule over the edge. Genuine overhangs hand off unchanged.
