+ * Decides whether this package's tests should run on the Node version in use.

+ * Exits 0 when they should be *skipped* and non-zero when they should run, so a caller can
+ * short-circuit with `node tools/skip-unsupported-node.js || <command>` and still report
+ * success on a skip. The inverted-looking exit code is deliberate: `&&` would make a skip
+ * indistinguishable from a test failure, and `!` negation is not available in the cmd.exe
+ * shell npm uses on Windows.
+ *
+ * This package needs a newer Node than the rest of the monorepo, so it opts itself out of
+ * the older CI matrix entries here. That keeps the workflow free of a hand-maintained list
+ * of workspaces to run, which would silently go stale as packages are added or their
