Introduce CI container and optimize workflows
- Added `.ci/container/Dockerfile` based on Ubuntu 24.04 with Java 8-25, Android SDK, and build tools. - Added `.github/workflows/build-container.yml` to build and push the container image. - Updated `.github/workflows/pr.yml`, `ant.yml`, `scripts-android.yml`, `parparvm-tests.yml` to use the new container. - Updated `scripts/setup-workspace.sh` to respect `CN1_BINARIES` and skip updates if needed. - Optimized dependencies installation by using pre-installed tools in the container.
