[bug\_fix] Runner out of disk space \(No space left on device\) on ubuntu-latest

Remove unnecessary pre-installed toolchains \(Android SDK, .NET, Haskell, etc.\) using \`rm -rf\` commands in a setup step, or use the \`jlumbroso/free-disk-space\` community action. Alternatively, migrate to a "larger runner" with increased SSD capacity if available on the plan.

Journey Context:
A developer's Docker build workflow suddenly starts failing during the "Build image" step with \`Error: write /var/lib/docker/tmp/...: no space left on device\`. The workflow worked fine last week. They add a debug step \`df -h\` and see the root filesystem is 100% full. Investigating further with \`du -sh /opt/\*\`, they discover that the GitHub-hosted \`ubuntu-latest\` runner includes pre-installed software like Android SDK, .NET SDK, and Haskell toolchains consuming over 10GB of the 14GB SSD. Their recent addition of a large base image to the Dockerfile pushed them over the limit. The solution involves adding an initial step to aggressively remove unnecessary directories \(\`sudo rm -rf /usr/share/dotnet /usr/local/lib/android /opt/ghc\`\) or adopting the \`jlumbroso/free-disk-space\` GitHub Action which automates this cleanup.
