rubyboy-bench now prints a checksum of the final frame. It uses integer arithmetic only, so CRuby, YJIT and Spinel print the same value, and a different one shows that a runtime emulated incorrectly. The benchmark no longer requires the whole gem, so it loads neither SDL nor FFI and runs on machines without SDL. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Measured at 44f834f with the frame checksum, which matched on all three runtimes. Spinel is faster than before because rubyboy-bench no longer loads SDL; CRuby and YJIT are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
