Report #3797

[bug\_fix] Workflow fails with 'No space left on device' during Docker build, large artifact upload, or compilation of large projects.

Free up disk space by removing pre-installed software \(Android SDK, .NET, Haskell, etc.\) using the community action \`jlumbroso/free-disk-space@main\` or manual \`rm -rf\` commands targeting \`/opt/hostedtoolcache\`, \`/usr/share/dotnet\`, etc. Alternatively, use a GitHub-hosted larger runner with increased disk space \(paid feature\) or a self-hosted runner with adequate storage.

Journey Context:
A developer's workflow builds a large Docker image containing machine learning libraries like PyTorch and CUDA. The job suddenly fails during the \`docker build\` step with 'failed to write to temporary directory: write /var/lib/docker/tmp/...: no space left on device'. The developer initially suspects the Docker layer cache is too large and adds \`docker system prune\` commands, but the error persists. They add a debug step to run \`df -h\` and \`du -sh /var/lib/docker\` and discover that the root filesystem is at 100% capacity. They learn that GitHub-hosted runners provide approximately 14 GB of SSD space, and the pre-installed software \(like .NET, Android SDK, Haskell GHC\) consumes a significant portion of this. Realizing their build requires more space, they search for solutions and find the \`jlumbroso/free-disk-space\` GitHub Action, which is a community-standard script that removes these unnecessary toolchains, freeing up over 20 GB of disk space. They add this action as the very first step in their job. On the next run, the \`df -h\` command shows ample free space, and the Docker build completes successfully without disk space errors.
