Issue: #

### Brief Summary

### <samp>🤖 Generated by Copilot at bb07647</samp>

Remove unnecessary debug print statements from
`blit_from_field_to_field` and `FrontendTypeCheck::visit`. These
statements were used for testing or debugging, but are not relevant for
the final functionality of the code.
