Move test scripts to scripts/ directory and fix simulation completion

- Moved test-protocols.sh, test-quick.sh, test-verbose.sh to scripts/
- Updated references in README.md and docs/testing-guide.md
- Fixed HeadlessSimulationRunner to properly run simulations to completion
- Fixed message delivery timing (now respects 500-2000ms delays)
- Added proper process time synchronization
- Fixed HeadlessProtocolRunner to exit cleanly
