Ensure test_dependencies directory exists for reliable artifact conso…

…lidation

One last attempt to fix things before moving on.

- Add step to create $HOME/test_dependencies if it doesn't exist, preventing cp errors.
- Consolidate workspace files (tooling and test_dependencies) into a common directory for artifact upload.
- Maintain consistent restoration across jobs by extracting the workspace artifact into $HOME.

This guarantees that all expected directories are present, avoiding failures during artifact consolidation and upload.
