Add danger-zone failure and console messages

Introduce a mock "danger zone" in the solver where rows with Length > 8.0 and Angle > 30.0 produce no signal (Signal set to None) and are counted as failed/crashed. Update solver output to report the number of crashed rows when present. Add informational prints to demo_optimise notifying users about the rigged failure and change the final dataset summary message to say "valid rows". This makes the Graveyard/blocking behavior visible during optimisation demos.
