Merge pull request 'test(m9): collapse ArgyllRunner waits under ICCERY_UI_TESTING' (#144) from feat/141-ui-test-timing into milestone/m9-monterey

Add a DEBUG-gated testAwareDelay helper (same ICCERY_UI_TESTING=1
convention as AppPaths.testRoot) and apply it to the ensureNotRunning
100ms poll and the XY chartread 500ms pre-kill wait. Under UI tests the
intervals shrink ~10x; release builds compile the branch out entirely,
so production timing is unchanged. No current UI test exercises XY
cancel, so the 500ms site is future-proofing at zero risk today.
