/**
 * Creates the PostGIS ST_DWithin (withinDistance) operator factory.
 *
 * ST_DWithin is special among PostGIS spatial operators because it takes
 * THREE arguments: (geom1, geom2, distance) instead of the standard two.
 * This requires a compound GraphQL input type (geometry + distance) rather
 * than just a geometry value.
 *
 * For geography columns, distance is in meters.
 * For geometry columns, distance is in the SRID's coordinate units.
 *
 * @example
 * ```graphql
 * query {
 *   restaurants(where: {
 *     location: {
 *       withinDistance: {
 *         point: { type: "Point", coordinates: [-73.99, 40.73] }
 *         distance: 5000
 *       }
 *     }
 *   }) {
 *     nodes { name }
 *   }
 * }
 * ```
