[bug\_fix] Error: EACCES: permission denied, rmdir '/home/runner/work/...' during checkout or cleanup

Configure the self-hosted runner as ephemeral \(set \` --ephemeral\` during configuration or use the \`ACTIONS\_RUNNER\_INPUT\_EPHEMERAL\` env var\) so the runner process exits after one job and the VM/container is destroyed/recreated, ensuring a clean state. Alternatively, run a pre-job cleanup script with elevated privileges \(via \`sudo\`\) to remove root-owned files from previous runs. Root cause: Self-hosted runners persist the filesystem between jobs; when Docker containers run as root, they create files owned by root that the runner's user \(non-root\) cannot delete in subsequent job checkouts, causing permission errors.

Journey Context:
Operations team sets up a persistent self-hosted runner on an internal VM. Developers create a workflow that uses a Docker container running as root to build artifacts. The first run succeeds, but subsequent runs fail at the \`actions/checkout\` step with "Error: EACCES: permission denied, rmdir '/home/runner/work/repo/repo/.git/objects/pack'". The team SSHs into the runner and finds directories owned by root. They manually run \`sudo rm -rf\` on the \`\_work\` directory and the job succeeds again, but the issue repeats. They research and find that GitHub recommends ephemeral runners for this exact reason. They reconfigure the runner with the \`--ephemeral\` flag and update their orchestration \(VM scale set\) to recycle the VM after each job. The permission errors stop because the filesystem is fresh for every job.
