Draw 1px yellow vertical lines between hosts when monitoring multiple
servers, making it easy to see where one host's bars end and the next
begins. Toggled with hotkey 's', persisted via 'w' to ~/.loadbarsrc.

Add a pink 1px line drawn from the top showing mean iowait+IRQ+softIRQ
across all hosts, toggled with hotkey i and persistable to ~/.loadbarsrc.
Also add m as alias for 2 (memory toggle) and n as alias for 3 (network
toggle) for easier single-hand operation.

Draw a 1px red horizontal line spanning the full window width showing
the mean CPU usage across all monitored hosts. Toggled with 'g' hotkey
and persistable to ~/.loadbarsrc via 'w'.
Bump version to 0.10.0.

Fixes issue where integer division (winW / numBars) left unused pixels
on the right side of the window. The more cores displayed, the more
obvious the gap became.
Changes:
- Add barBounds() helper to calculate exact position and width for each bar
- Distribute remainder pixels evenly using scaled division
- Update drawing functions to use pre-calculated positions
- Update test to verify bars now fill entire window width
Increment version to 0.9.1

Sum RX/TX across all non-lo interfaces instead of picking a single one.
Remove the n hotkey (cycle interface), netint config field, and --netint
flag since they are no longer needed. Fix pre-existing bug where net bars
decayed to zero between collector updates (~19 of 20 frames had target=0,
making bars invisible even during heavy downloads).

Add missing f/v hotkey handlers to cycle NetLink through
mbit/10mbit/100mbit/gbit/10gbit, closing the gap between README
documentation and actual implementation. Add 13 unit tests covering
all hotkey behaviors including visual pixel assertions for toggles.

drawFrame() only cleared the window on layout changes, leaving remainder
pixels (from integer division winW/numBars) with stale content from the
double-buffered back buffer. Now clears every frame per SDL2 best practice.
Adds comprehensive SDL visual test harness using software renderer with
pixel spot-checking for CPU, memory, network bars, and the remainder bug.
