chore(filesystem): capture latest filesystem changes

- Removed multiple toolbox directories (toolbox-QADocker, toolbox-dockstack, toolbox-qadocker)
- Created new toolbox-docstack directory
- Added .gitkeep to toolbox-qadocker directory to keep it tracked in git
- The filesystem structure continues to be the authoritative source of truth
- Preserved toolbox-qadocker directory in git with .gitkeep as requested for future work
