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

+
+## 🎯 Purpose
+Specialized documentation generation toolbox for creating beautiful PDFs including resumes, proposals, Joplin note exports, and timelines.
+
+## 🧰 Tooling Goals
+1. **Core Documentation Tools**
+   - Pandoc for document conversion
+   - PlantUML for UML diagrams
+   - Graphviz for diagram rendering
+   - Markwhen for timeline creation
+
+2. **PDF Generation Frameworks**
+   - Quarto for scientific and technical documents
+   - mdBook for book-style documentation
+   - Marp for presentation slides
+   - Typst for modern typesetting
+
+3. **AI-Assisted Documentation**
+   - Joplin CLI for note management and export
+   - Code generation tools for AI-assisted writing
+
+4. **Verification & Quality**
+   - Document validation and linting
+   - Automated testing of document generation workflows
+
+## 🏗️ Implementation Plan
+1. Extend from the toolbox-base image
+2. Install documentation-specific packages via apt
+3. Add documentation tools via aqua where available
+4. Install Node.js-based tools via npm/mise
+5. Ensure all tools work together in a cohesive workflow
+6. Provide comprehensive testing and verification
+
+## 🧪 Testing Expectations
+- Verify all documentation tools can generate output
+- Test document conversion workflows (Markdown → PDF, etc.)
+- Validate diagram generation (PlantUML, Graphviz)
+- Confirm timeline creation with Markwhen
+- Ensure PDF generation with all frameworks (Quarto, mdBook, Marp, Typst)
+
+## 📚 Documentation Requirements
+- Update README with all installed tools and usage examples
+- Document common workflows for each tool category
+- Provide troubleshooting guidance for PDF generation issues
+- Include examples for resumes, proposals, and note exports
