- Update product documentation with accurate current status
- Add AI agent documentation (.cursorrules, .gooserules, guides)

Documentation Reorganization:

- Create 6 organized directories with README files
- Add navigation guides and cross-references

Product Documentation Updates:

- AI agents can work more effectively
- Improved onboarding for contributors

Statistics:
- Files organized: 71
- Files created: 11 (6 READMEs + 5 AI docs)
