Subject: [PATCH] ci: add JaCoCo coverage gate and Gitea CI pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add JaCoCo maven plugin (0.8.11) with prepare-agent, report, and check goals
- Set 50% bundle-level line coverage gate (to be raised as test coverage grows)
- Exclude UI classes (App, Controller, ShapesView, etc.) from coverage checks
  since they require a display and cannot be unit-tested
- Add Gitea Actions workflow: checkout → JDK 16 → mvn verify → upload report

Closes #14
