feat: add JaCoCo + Coveralls + Codecov; refactor post-publish into report job before Maven Central

Add JaCoCo 0.8.14 plugin to pom.xml (prepare-agent + report in test phase).
Upload jacoco.xml artifact from test-java-linux-x86_64. Rename post-publish to
report, run it after package and before publish-snapshot/publish-release.
Step order: dependency submission, Coveralls, Codecov.
