docs: add author metadata and complete planning directory README

Fixed missing author attribution in documentation files and created
comprehensive README for planning directory.

Author attribution updates:
- docs/development/CONVERSATIONAL_AI_IMPLEMENTATION.md
- docs/reports/IMPLEMENTATION_SUMMARY_2025_09_16.md
- docs/planning/README.md
- All files now properly credited to Anderson Henrique da Silva

New documentation:
- docs/planning/README.md (150 lines)
* Strategic planning overview
* Available documents index
* Sprint process description
* Current status and roadmap highlights
* Planning principles and quick links

Impact: All documentation now has proper attribution and the planning
directory has clear navigation structure.
