[bug\_fix] GitHub Actions workflow fails with 'No space left on device' during Docker builds, package installation, or artifact generation

Free up disk space by removing pre-installed software that isn't needed \(Android SDK, .NET, Haskell, etc.\) using \`rm -rf\` commands, or use \`docker system prune -f\` to clean up dangling images between steps. For persistent large storage needs, mount an external volume or switch to a self-hosted runner with larger disks. Root cause: GitHub-hosted runners \(especially \`ubuntu-latest\`\) provide approximately 14-15GB of free disk space; large Docker images, multi-gigabyte dependencies \(Android NDK, ML models\), or accumulated build artifacts quickly exhaust this limit.

Journey Context:
A development team sets up a CI pipeline to build a React Native application. The workflow installs the Android SDK, NDK, and builds the native code using Gradle. Initially, the builds pass, but after adding more native dependencies and Docker layer caching, the workflow starts failing consistently with 'No space left on device' during the Gradle packaging step. The team tries adding \`df -h\` to the workflow and sees the root filesystem is 100% full. They investigate and find that the Android SDK alone takes 8GB, and Docker images are consuming another 6GB. They search for solutions and find community 'maximize-build-space' actions that remove pre-installed .NET, Haskell, and Android SDKs \(since they're reinstalling specific versions anyway\). They add a step to run \`rm -rf /usr/share/dotnet /usr/local/lib/android/sdk\` and \`docker system prune -f\` at the start of the job. This frees up 20GB of space, allowing the build to complete successfully without switching to paid larger runners.
