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
