Subject: [PATCH] fix: write dependency-reduced-pom.xml to target/ to prevent
 incremental build issues

The maven-shade-plugin writes dependency-reduced-pom.xml to the project root
by default. On subsequent builds without clean, Maven reads this file instead
of pom.xml, loses protobuf/gRPC dependencies, and produces a JAR without
StreamingMessage and other generated gRPC classes.

Setting dependencyReducedPomLocation to target/ ensures clean deletes it and
incremental builds always use the real pom.xml.
