Introduce two reactor modules that exist purely to host repository-wide
test concerns:
- dc3-coverage (packaging=pom) runs jacoco:report-aggregate against all
contributing modules and applies a tree-wide jacoco:check rule. The
aggregator excludes generated sources, deployable Application classes,
POJO entity packages and the third-party modbus4j sero utilities so
the percentage stays anchored on real business logic. Coverage gates
start at 0% and tighten in later stages as more tests land.
- dc3-e2e (packaging=jar) reserves a place for the docker-compose driven
end-to-end suite delivered in stage S8. Unit and integration phases
are skipped by default and only the e2e profile turns them on.
Both modules are wired into the root reactor.
