fix: resolve CLI documentation duplication between beginner and technical docs

DUPLICATE RESOLVED:
- Fixed confusion between /docs/beginner/05_cli/ and /docs/cli
- Renamed symlink to clarify purpose and eliminate duplication

CHANGES MADE:
✅ Removed: /docs/cli (symlink to /cli/docs)
✅ Created: /docs/cli-technical (symlink to /cli/docs)
✅ Updated: Documentation to reflect the change

CLARIFIED STRUCTURE:
/docs/beginner/05_cli/          # CLI beginner documentation (detailed guides)
├── README.md                   # Comprehensive CLI guide for beginners
├── permission-setup.md         # CLI permission setup
└── testing.md                  # CLI testing guide

/docs/cli-technical -> /cli/docs # CLI technical documentation (symlink)
├── README.md                   # CLI technical documentation
├── DISABLED_COMMANDS_CLEANUP.md
└── FILE_ORGANIZATION_SUMMARY.md

BENEFITS:
🎯 Clear separation: Beginner guides vs technical implementation
📚 No confusion: Distinct naming for different purposes
🔍 Easy navigation: Obvious which docs to use for which need
✅ Preserved content: All documentation remains accessible

VERIFICATION:
✅ Both documentation types accessible
✅ No broken links or missing files
✅ Clear naming convention established
✅ Documentation updated to reflect changes

STATUS: Duplicate resolved - CLI docs now properly categorized
