A read-only storage topology visualizer, disk queue geometry inspector, and filesystem mountpoint capacity analyzer for Linux. A lightweight Linux alternative to DiskExt for mapping disks to partitions, active mountpoints, inode utilization, and swap spaces using standard read-only kernel interfaces.

Key features:

• Maps physical and virtual disks to child partitions and active mountpoints using /proc/partitions, /proc/mounts, /proc/swaps, and /sys/class/block attributes.
• Renders a visual Disk-to-Partition-to-Mountpoint allocation diagram alongside live filesystem byte capacity and inode utilization bars via statvfs.
• Inspects sysfs block queue geometry including logical vs physical sector sizes, rotational (HDD vs SSD/NVMe) flags, read-only state, and hardware model strings.
• Parses VFS and filesystem mount options with human-readable flag descriptions and exports full storage topology reports to JSON and CSV.
