+    <description>
+        Non-published reactor aggregator. Builds the library plus the examples
+        and benchmarks modules in one pass and gives a single entry point for
+        `versions:set`, so a version bump propagates to every module at once.
+        This is NOT a Maven parent and is NOT published to JitPack: the library
+        root pom.xml stays standalone so consumer coordinates never change.
+
+        Usage:
+          mvn -f aggregator/pom.xml -DskipTests install        # build everything
+          mvn -f aggregator/pom.xml versions:set -DnewVersion=X # bump all modules
