Find out why a disk is full and what can safely be freed, using the HyperDU scanner. Use when a drive is out of space, a build fails with "no space left on device", or the user asks what is using their disk, which directories are largest, or what is safe to delete. Covers per-volume free space, largest-directory scans, and separating regenerable build output (Cargo target, node_modules, virtualenvs) from data that cannot be rebuilt.
