style(startup): use universal console splash

Replace the temporary ASCII-art banner with a structured startup splash that uses plain ASCII, aligned fields, and no ANSI or terminal-specific features. This keeps the emulator startup readable across CMD, PowerShell, Linux terminals, Docker logs, CI output, and copied log files. Add a contract test to keep the splash universal.
