P0 - Division by zero fixes:
- Clamp PhysMaterial->Density to min 0.001 before division
- Clamp MuzzleVelocity averages to min 1.0 in all divisions
- Clamp PhysMaterial->Restitution to [0, 1]
P1 - Edge case guards:
- Stop bullet immediately when velocity is near-zero (prevents NaN)
- Handle near-zero cross product at very shallow grazing angles
- Handle zero-length bounceAngle in ricochet calculation
P2 - Improvements:
- Fix typo: BlockTIme -> BlockTime
- Add incidence angle factor to penetration depth: grazing shots
penetrate less (5% at ~5deg) while head-on shots get full depth
