CollisionMapper2D

Responsibilities:

• Translate CollisionShape2D / CollisionPolygon2D geometry into tile offsets used by placement rules and indicators.
• Apply filtering, normalization, and heuristics to remove slivers and normalize pivots for consistent indicators.
• Provide caching and utility helpers consumed by IndicatorManager and the placement pipeline. See: Collision Mapping guide
