Add a new disk stats category that reads /proc/diskstats, shows read/write
throughput as colored bars (purple/darker purple like network RX/TX), with
optional utilization % overlay in extended mode. Hotkey 5 cycles: aggregate
(sum all whole-disk devices) → per-device → off. Auto-scale with decay and
optional fixed override via --diskmax / diskmax config key.

- config: split set() (62L) into setSizeAndTuning() + setDisplayFlags()
- collector: split Run() (70L) into Run + startLocalScanner + startRemoteScanner
+ parseCollectorStream + dispatchCollectorLine; each <30L
- collector: remove unused script_embed.go (RemoteScript was dead code)
- display: move newRunState constructor before Run() per constructor-first rule
- display: replace loadPeak IIFE with a plain initLoadPeak variable
- display: split handleKey() (114L) into handleToggleKeys + handleAdjustAndSave
+ handleResizeKeys; add nil guard in handleResizeKeys for test safety
- display: split drawNetBarSmoothed() (75L) into drawNetBarSmoothed +
smoothNetUtilization + drawNetHalves; each <30L
- all: gofmt -w to fix formatting drift in display and config files
All tests pass (go test ./...).

- config: add LoadMax float64 field; loadmax key in ~/.loadbarsrc; written by 'w'
- main: add --loadmax flag (overrides rc file when > 0)
- display: newRunState initialises loadPeak from LoadMax when fixed
- display: updateLoadPeak accepts loadMax param; short-circuits to fixed value when set
- display: add 'r' hotkey to reset auto-scale peak to floor (2.0); no-op when fixed
- tooltip: loadTooltipLines shows 'Max:' label when scale is fixed, 'Peak:' for auto
- README: document 4/l load toggle, r reset, --showload, --loadmax, load average bars section; fix --cpumode entry

Adds a new teal bar type showing /proc/loadavg data per host.
The 1-min average fills from the top downward; yellow and white
1px reference lines mark the 5-min and 15-min averages. A global
loadPeak tracker (floor 2.0, slow per-frame decay) keeps the scale
meaningful across hosts and after spikes. Toggle with 4 or l;
persisted to ~/.loadbarsrc as showload=1.
Bump version to 0.12.0.

CPU display now cycles through three states with each press of 1:
0 = CPUModeAverage – aggregate bar only (default)
1 = CPUModeCores – individual core bars + aggregate
2 = CPUModeOff – all CPU bars hidden
Config file stores cpumode=N (integer); old showcores=0/1 is read for
backward compatibility. CLI flag --showcores replaced by --cpumode.
Other improvements landed in this commit:
- internal/display: add font.go (text rendering), hittest.go (bar hit
testing), tooltip.go (mouse-over tooltip), tooltip_test.go
- internal/display: mouse tracking and drawOverlay hook in display.go
- internal/display: update build tags to //go:build form
- internal/collector: embed remote script via script_embed.go /
scriptdata/loadbars-remote.sh
- internal/collector: CPULine.Total() changed to value receiver
- internal/collector: table test improvements (name field, t.Run)
- internal/constants: BytesPerSec consts promoted from var to const
- Magefile.go: fix error formatting and install path

When monitoring many servers, bars can become too thin to read. The new
maxbarsperrow setting (default 0 = unlimited) wraps bars into multiple
rows of equal height when the count exceeds the limit. The last row may
have fewer, wider bars filling the full window width.

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.

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).
