/*
 * Report-only performance baseline for the text and trigger pipelines, for the
 * libmudlet refactor's "no more than 10% throughput loss" gate (issue #9011).
 *
 * Absolute numbers are meaningless across machines, so nothing is asserted on
 * timing and no baseline is committed: the gate is enforced by comparing an
 * older and a newer build of this binary on the SAME machine with
 * test/compare-perf-baseline.py. The benchmark feeds a fixed, deterministic
 * corpus through the production cTelnet::loopbackTest() path and prints one
 * `METRIC <name> <value>` line per measurement.
 *
 * `text_*`, `trigger_*` and `peak_rss_kb` come from a profile with the default
 * packages suppressed; `defaults_*` from one carrying them.
 *
 * Built with the functional tests but deliberately NOT registered with ctest by
 * default (report-only and slow); run it directly, or configure with
 * -DREGISTER_PERF_BENCHMARK=ON to also get it under ctest:
 *   QT_QPA_PLATFORM=offscreen ./PipelineBenchmark
 *
 * Companion for the live-GUI display/echo path is the Stressinator display
 * package; see docs/libmudlet-perf-baseline.md.
