xgopilot 2b92b527e1 fix: resolve compilation errors in maphash demo
- Fix line 67: Change unused variable 'n' to blank identifier '_'
- Fix line 102: Correct WriteByte call to expect only error return value
  (WriteByte returns only error, not (int, error))

These fixes resolve the compilation errors reported by the CI.
