serge_shubin 043e3a2def QL stair traversal: conditional velocity clip + air steps 
Two changes to PM_StepSlideMove that transform stair traversal:

1. Remove Q3 velocity[2]>0 gate (QL pm_airSteps): allow step-ups
   while airborne, enabling bunny-hop stair traversal.

2. Conditional velocity clip: only clip velocity to step-down surface
   when moving INTO it (dot product < 0). Skip clip when velocity is
   moving away (dot >= 0), preserving upward momentum through steps.
   This is THE key mechanic for smooth QL-style stair hopping.

Also adds 100ms jump cooldown (lastJumpTime) to prevent same-frame
double-fires during rapid step-ups.
