/**
 * PCD (PCL) streaming source — whole-file decode, single chunk.
 *
 * Like PLY, PCD isn't an octree format. The decoder lives in
 * `formats/pcd.ts` and handles ASCII / binary / binary_compressed
 * (LZF). For files past the 25M-point soft cap, `streamPointCloud`
 * applies stride downsampling on the way out.
