Release v0.10.1

Release Notes

Loadbars v0.10.1 adds new visual overlays for I/O monitoring and multi-host clarity, more intuitive hotkeys, and displays the GuestNice CPU metric.

Global I/O average line (hotkey i) — A 1px pink horizontal line showing the mean iowait + IRQ + softIRQ across all hosts, making it easy to spot I/O pressure at a glance.
Host separator lines (hotkey s) — 1px yellow vertical lines drawn between hosts when monitoring multiple machines, so you can instantly see where one host's bars end and the next begins.
GuestNice CPU segment — The GuestNice metric is now visualized as a lime green segment in CPU bars, giving full visibility into virtualized workload overhead.

Hotkey aliases — Memory bars can now be toggled with m (in addition to 2) and network bars with n (in addition to 3), making hotkeys easier to remember.
Persistent settings — The new showioavgline and showseparators options are saved/restored via ~/.loadbarsrc when pressing w.
Code quality — Aligned codebase with Go best practices (ordering, style) and added comprehensive unit tests for all new features including I/O avg line rendering, separator drawing, hotkey toggling, and config round-trips.

All existing hotkeys, config files, and command-line options continue to work as before.
