 * Memory-as-Physics engine: pure math (forces, Velocity Verlet integration, physics-based scoring, cluster
 * amplification), no I/O.
 * Memories are particles on the unit hypersphere in embedding space (384-dim); query gravity, attraction, conflict
 * repulsion and drag act on them,
 * and nearby high-scoring memories amplify each other. */
