Disk I/O: collect stats on remote, dynamic bar count, reset peak on r
- Add M DISKSTATS block to embedded loadbars-remote.sh so disk I/O is
collected from /proc/diskstats on remote hosts (was only in scripts/ copy).
- Document in countBars that total bars are computed per host (dynamic
device count when disk mode is per-device).
- Extend r hotkey to reset disk auto-scale peak to 1 MB/s floor when disk
bars are on and diskmax is not fixed; update README and help text.
