ProjectionSpatialModel

Adapter that exposes an agent-layer ContinuousProjection as a spatial-layer SpatialModel. This is the bridge that lets entity-layer code requiring a LocationIfc (notably MovableResource and the KSLProcess.move() family) operate in the same coordinate space as agent-layer code.

Usage:

val space = ContinuousProjection<MyAgent>(context, 0.0..100.0, 0.0..100.0)
val sm = space.asSpatialModel()
val forklift = MovableResource(parent, sm.location(50.0, 50.0), ...)

Behavior:

• Distance uses the projection's own metric (Euclidean, with torus wrap if enabled).

• compareLocations uses Point2D structural equality.

• Locations created via location carry agent-layer Point2D values, retrievable via LocationIfc.toPoint2D.

Scope of the bridge (deliberate limitations):

• One-way reuse of geometry, not full integration. The bridge lets entity-layer types share coordinates with the projection, but moving a MovableResource does not automatically update the projection. Agent positions (projection.moveTo(agent, ...)) and movable-resource positions (movableResource.currentLocation = ...) are independent even when they share coordinates.

• Each call to ContinuousProjection.asSpatialModel produces a new ProjectionSpatialModel. Locations created in one are not valid for another. Call once and store the result.

Deeper integration — including a MovableResource whose position is the projection's source of truth — is a separate future track (Phase 4.4 in the design doc).
