描述

Is your feature request related to a problem? Please describe. On FreeBSD, top is an extremely useful utility. One of its features is that when ZFS is in use, top displays a summary of ARC statistics.

Describe the solution you'd like It would be nice to be aware of ZFS and provide some ARC stats like top does on FreeBSD. Making the disks panel understand pools and datasets and vdev iostats could be nice, too.

Describe alternatives you've considered I'll just use the standard top for when I need something more utilitarian than pretty.

研究方向
To implement ZFS awareness, first understand how bpytop currently gathers system statistics (likely via psutil or direct file reads). For ZFS ARC stats on FreeBSD, you'll need to read values from sysctl (e.g., `kstat.zfs.misc.arcstats`) or from procfs (`/proc/spl/kstat/zfs`). Look at the existing disk panel to see how it handles i/o stats and consider adding a similar panel for ZFS pools and datasets. Review the issue comments for any maintainer hints or design discussions. The main source file is likely `bpytop.py` or a module like `disks.py`.
