Description

Implement zones that affect entities (fire, poison gas, music).

Acceptance Criteria

Scenario: Trigger volumes work
  Given world has trigger volumes
  When entity enters volume
  Then entity is affected by volume (damage, healing, mood change)
  And effects persist while in volume
  And effects cease after leaving volume

Technical Notes

Trigger volume shapes: box, sphere, polygon
Effect types: damage, heal, mood, condition
Entry/exit events
Continuous effects while inside
Spatial indexing for efficient queries
Multiple overlapping volumes

Size: S (2 points)
Priority: P1
Phase: 5 - World Substrate
