docs: consolidate CLI documentation and purge legacy structure

MERGE OPERATIONS:
- Merged /opt/aitbc/cli/docs into /opt/aitbc/docs/cli
- Eliminated duplicate CLI documentation locations
- Created single source of truth for CLI docs

ORGANIZATION IMPROVEMENTS:
- Created structured subdirectories:
  • implementation/ - Core implementation summaries
  • analysis/ - Analysis reports and integration summaries
  • guides/ - Installation and setup guides
  • legacy/ - Historical documentation (archived)

- Updated main README.md with:
  • New consolidated structure overview
  • Updated installation instructions for flat CLI structure
  • Recent CLI design principles changes
  • Proper navigation to subdirectories

- Created legacy/README.md with:
  • Clear deprecation notice
  • File categorization
  • Purge candidates identification
  • Migration notes from old to new structure

FILE MOVES:
- 15 implementation summaries → implementation/
- 5 analysis reports → analysis/
- 3 setup guides → guides/
- 19 legacy documented files → legacy/
- 1 demonstration file → root (active reference)

PROJECT DOCUMENTATION UPDATES:
- Updated /docs/beginner/02_project/1_files.md
- Reflected flattened CLI structure (cli/commands/ vs cli/aitbc_cli/commands/)
- Added docs/cli/ as consolidated documentation location
- Updated Python version requirement to 3.13.5 only

BENEFITS:
- Single location for all CLI documentation
- Clear separation of current vs legacy information
- Better organization and discoverability
- Easier maintenance and updates
- Proper archival of historical documentation

STATUS:
✅ Consolidation complete
