Display 'game lost' reason

The player does not know why he lost a game, we could display that to him easily

No files or tests are named in the report. Start in the game flow logic that determines when a loss occurs, then locate where the 'game lost' message is emitted to the player. Follow that path end-to-end to include the computed loss reason in the displayed output. Verify by running the repository’s test suite (if available) and a manual losing playthrough to confirm the reason appears.
