Detailed Description

Emits log messages at a configurable rate, severity mix and shape, to put the logging path (LogSender -> IceStorm "Log" topic -> LogViewer GUI) under a reproducible load.

Every message is unique: the text is assembled from random words plus a per-thread counter and a random id. That matters because the viewer deduplicates nothing and because identical lines would not exercise its per-entry work realistically.

The knobs are chosen to reach the parts of the path that actually cost something:

WarningPercent / ErrorPercent – messages at WARN and above carry a full backtrace (see LogSender::log), which dominates both payload size and sender cost.
MultilinePercent – multi-line messages are what give the viewer's table rows individual heights.
TagCount – spreads messages over several tags.
ThreadCount – concurrent senders, so the global console mutex in LogSender is contended as it is in a real component.
BurstEveryMs / BurstSize – periodic bursts on top of the steady rate, to exercise the viewer's staging queue rather than only its steady-state throughput.

The component name shown in the viewer is the application name, so a scenario runs several instances of this app to produce several distinct log sources.
