Add organized Docker container structure with disciplined naming

- Create layered container architecture: Base, Light, Full, Computational
- Implement non-root user management with UID/GID mapping
- Add Markwhen timeline tool to documentation stack
- Create wrapper scripts for environment variable handling
- Update documentation across all containers
- Establish naming convention using RCEO-AIOS-Public-Tools- prefix
- Add organizational rule to keep repository root clean
- Remove old unorganized container files

+# TODO List for RCEO-AIOS-Public-Tools-DocMaker Containers
+
+This document tracks potential enhancements and tools to be added to the documentation generation container family.
+
+## Container Structure
+
+### RCEO-AIOS-Public-Tools-DocMaker-Base
+- Base documentation environment with lightweight tools
+- Purpose: Foundation for all other containers
+
+### RCEO-AIOS-Public-Tools-DocMaker-Light
+- Lightweight documentation tools (no heavy LaTeX)
+- Purpose: Fast-starting documentation tasks (COO mode)
+
+### RCEO-AIOS-Public-Tools-DocMaker-Full
+- Full documentation environment with LaTeX-full
+- Purpose: Complex document generation (COO mode)
+
+### RCEO-AIOS-Public-Tools-DocMaker-Computational
+- All documentation tools plus R, Python, Jupyter, Octave
+- Purpose: Computational tasks and analysis (CTO mode)
+

+
+## Completed Items
+
+### Base Container Tools
+- ✅ Core system packages (bash, curl, wget, git)
+- ✅ Programming languages (Python 3, Node.js, Rust)
+- ✅ Pandoc - Universal document converter
+- ✅ mdBook - Create books from Markdown files
+- ✅ mdbook-pdf - PDF renderer for mdBook
+- ✅ Typst - Modern typesetting system
+- ✅ Marp CLI - Create presentations from Markdown
+- ✅ Markwhen - Interactive text-to-timeline tool
+- ✅ Light LaTeX packages (texlive-latex-base) 
+- ✅ Spell/grammar checking tools (Hunspell, Aspell, Vale)
+- ✅ Text statistics tools (mdstat)
+- ✅ Non-root user management with UID/GID mapping
+- ✅ Entrypoint script for runtime user creation
+
+### Full Documentation Container Tools
+- ✅ All Base Container tools included
+- ✅ Full LaTeX (texlive-full) - for complex document generation
+
+### Computational Container Tools
+- ✅ All Full Documentation Container tools included
+- ✅ R programming language and common packages
+- ✅ Python scientific stack (pandas, numpy, matplotlib, scipy)
+- ✅ Jupyter Notebooks with R kernel support
+- ✅ GNU Octave
+- ✅ Command-line calculator (bc)
+
+### Organizational Improvements
+- ✅ Disciplined naming convention using RCEO-AIOS-Public-Tools- prefix
+- ✅ Individual directories per container type
+- ✅ Proper documentation with individual README files
+- ✅ Organized docker-compose files per container
+- ✅ Clear separation of COO vs CTO mode containers
