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

Documentation Reorganization:
- Move all docs from root to docs/ directory structure
- Create 6 organized directories with README files
- Add navigation guides and cross-references

Product Documentation Updates:
- STATUS.md: Update from 2026-02-15 to 2026-03-09, fix all phase statuses

- PROGRESS.md: Create new progress dashboard with visual tracking
- encryption.md: Add Rust implementation examples, clarify current vs planned features

AI Agent Documentation:
- .cursorrules: Project rules for AI IDEs (Cursor, Copilot)
- .gooserules: Goose-specific rules and workflows
- docs/AI_AGENT_GUIDE.md: Comprehensive 17KB guide
- docs/AI_QUICK_REFERENCE.md: Quick reference for common tasks
- docs/AI_DOCS_SUMMARY.md: Overview of AI documentation

Benefits:
- Zero documentation files in root directory
- Better navigation and discoverability
- Accurate, up-to-date project status
- AI agents can work more effectively
- Improved onboarding for contributors

Statistics:
- Files organized: 71
- Files created: 11 (6 READMEs + 5 AI docs)
- Documentation added: ~40KB
