Wire the test toolchain into developer-facing entry points and CI:
- Makefile gains test, test-it, test-e2e and coverage targets; the help
banner advertises them alongside the existing build commands so
contributors do not need to memorise the underlying mvn invocations.
- A new Test workflow runs three sequenced jobs: unit (mvn test, skipping
the integration phase), integration (mvn verify, skipping unit phase,
running with TESTCONTAINERS_REUSE_ENABLE=true), and a final coverage
job that downloads both jacoco .exec artifacts and rebuilds the
aggregate report from dc3-coverage.
- A new E2E workflow runs make test-e2e on develop/release/main pushes
and on manual dispatch, with a 90 minute timeout that accommodates
cold compose start-up plus the full critical path battery.
- The existing CI workflow keeps its fast-fail compile job unchanged so
PR feedback latency stays low; tests are now owned exclusively by
the new Test workflow.
