Update and organize documentation

- Renamed all uppercase markdown files to lowercase for consistency
  - ARCHITECTURE.md -> architecture.md
  - DEVELOPER_GUIDE.md -> developer-guide.md
  - TIMESTAMP_EVENTS_GUIDE.md -> timestamp-events-guide.md
  - SERIALIZATION_NOTES.txt -> serialization-notes.txt

- Removed all Raft references from documentation
  - Updated build-fixes-summary.md
  - Updated testing-guide.md
  - Updated test-infrastructure.md
  - Updated simulation-builder-framework.md

- Created index.md for easy documentation navigation
  - Organized docs by category (Architecture, Testing, GUI Decoupling, etc.)
  - Added quick links for different user types
  - Included documentation standards and contribution guidelines

All documentation is now consistent and up-to-date with the current codebase.
