Subject: [PATCH] Fix CI disk space issues by running tests sequentially with
 cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The java-runner and android-runner molecule tests were failing due to
running out of disk space on GitHub Actions runners. Both tests pull
the compscidr/github-runner-android image which is ~15GB and includes
the full Android SDK/NDK.

Changes:
- Run molecule tests sequentially (max-parallel: 1) instead of in parallel
- Add disk cleanup step before tests to free up ~10-15GB by removing
  unused software (.NET SDK, GHC, Boost, agent tools)
- Add Docker cleanup after each test to ensure space for next test
- Clean up Docker images and volumes between tests

This ensures each test has sufficient disk space without modifying
the actual runner images or test scenarios.

Fixes failing PRs #35, #34, #33, #32, #28
