 * Register the trigger property handler.
 *
 * Supports the following property on scene nodes:
 * - `trigger` (string): The trigger zone name
 *
 * When an object enters or exits the trigger zone, events are published:
 * - `trigger:enter` with payload { trigger: string, other: AbstractMesh }
 * - `trigger:exit` with payload { trigger: string, other: AbstractMesh }
 *
 * The trigger mesh is made invisible but retains collision detection.
 * Intersection checks are registered against all non-trigger meshes in the scene,
 * including meshes added after the handler runs (e.g. dynamically spawned entities).
