[bug\_fix] No space left on device during Docker builds or large dependency installations on hosted runners

Add cleanup steps at the beginning of the job to remove unnecessary pre-installed tools and temporary files. Use actions like easimon/maximize-build-space or manual cleanup commands \(rm -rf /opt/hostedtoolcache, /usr/share/dotnet, /opt/ghc, /usr/local/lib/android\) to reclaim 10-15 GB of space. GitHub-hosted ubuntu-latest runners provide approximately 14 GB of SSD storage, which is partially consumed by the operating system and numerous pre-installed SDKs \(multiple .NET versions, Java, Android SDK, Haskell, etc.\).

Journey Context:
A developer maintains a microservices application with multiple Docker images. They set up a GitHub Actions workflow that builds several Docker images in sequence. Initially, the workflow runs successfully. As the project grows and more dependencies are added, the workflow starts failing intermittently during the Docker build step with errors like "write /var/lib/docker/tmp/...: no space left on device" or "no space left on device" during npm install. The developer checks the GitHub-hosted runner documentation and sees that ubuntu-latest has 14GB of SSD. They attempt to run docker system prune -af in a cleanup step, but the failure occurs before this step can run, or there's still insufficient space. They investigate the runner image specifications and discover that the pre-installed software \(multiple versions of .NET, Java, Android SDK, etc.\) consumes significant disk space. They find community solutions like the easimon/maximize-build-space action or manual cleanup scripts that remove /opt/hostedtoolcache, /usr/share/dotnet, /opt/ghc, and /usr/local/lib/android at the beginning of the job. Implementing this cleanup frees up approximately 10-15 GB of disk space, allowing the Docker builds to complete successfully without disk space errors.
