Subject: [PATCH] Fix macOS nightly smoke failures for pdf-standard and Julia
 plot tests

The nightly macOS leg is the first time the smoke suite runs on macOS, and it hit two gaps unrelated to the built binary.

veraPDF was only installed on Linux, while the pdf-standard fixtures only exclude Windows. ua-missing-title is the one fixture that asserts on veraPDF's own output, so on macOS it rendered without validation and the expected WARN never appeared. The runner ships Java 21, so veraPDF installs fine there.

The Julia crossref figure tests plot with Plots/GR. GR.jl does not recognize a julia-engine (QuartoNotebookRunner) worker as an embedded display, so on macOS GKS launches its interactive gksqt window. On the headless runner gksqt does not reliably start, and the render either blocks until the 10 minute test timeout or the worker dies. This is a GR/QuartoNotebookRunner behavior to be reported upstream, so these four tests are skipped on macOS for now.
