Implement headless testing framework for DS-Sim protocol simulations

- Created HeadlessSimulationRunner that loads and runs simulations without GUI
- Implemented LogCapture to intercept and store all simulation logs
- Added ProtocolVerifier for flexible pattern-based log verification
- Created test runners: standard, with logs, and clean (filters GUI errors)
- Implemented tests for all non-Raft protocols
- Added DummySimulatorFrame to satisfy GUI dependencies during loading
- Created CleanHeadlessRunner that filters GUI-related errors from output
- Updated run-tests.sh script with quiet mode option
- Documented the framework architecture and usage

The framework successfully runs protocol tests and verifies behavior through
log analysis. GUI errors occur internally due to tight coupling in DS-Sim
but are filtered in quiet mode for clean output.
