100K+ Pedestrian Crowd Simulation in Unity DOTS | Traffic Engine

DOTS Crowd Simulation Update: Traffic Signals, Physics & Multi-Layer Avoidance Working! 🚶‍♂️🚦

✅ What's New :
🚦 Traffic Signal Integration - Agents properly queue at red lights, detect signal changes, and flow naturally when green. The queuing system uses forward cone spatial analysis to detect congestion vs actual traffic stops.
🏗️ Multi-Layer Obstacle Avoidance - Two separate systems working in harmony:

Agent-to-agent avoidance with state-aware modulation (moving vs queuing agents behave differently)
Static obstacle avoidance using forward box casting with agent radius consideration

🪜 CharacterController-Style Physics - Agents can walk on stairs, handle elevation changes, and fall realistically. Surface detection works across ground/stair layer masks with proper step height limits.
🧠 Lane-Aware Navigation - Agents understand adjacent lanes, opposite-direction lanes, and boundary constraints. They can transition between lanes while respecting traffic rules.
