/**
 * Describe a world so an agent can plan a build: bounds, materials, a coarse
 * height map, recent builds, and (optionally) the exact blocks in a region.
 *
 * @param input - `{ room, region?: { minX, maxX, minY, maxY, minZ, maxZ } }`. room is the room link or code; without room or worldId it describes the main world.
 * @returns World summary with `rules` (bounds, materials) to follow when placing blocks.
 * @example
 * import describeWorld from 'kody:@kentcdodds/world-builder/describe-world'
 * const info = await describeWorld({ room: 'abc123defg', region: { minX: -8, maxX: 8, minY: 0, maxY: 10, minZ: -8, maxZ: 8 } })
