clean up: explicit utf-8 encoding, proper exception handling, remove dead code

- Add encoding="utf-8" to all file writes
- Catch requests.RequestException instead of bare except
- Use raise_for_status() to also retry on HTTP errors
- Use removeprefix/removesuffix instead of lstrip/rstrip
- Use makedirs(exist_ok=True)
- Remove unused common_suffix function and commonprefix import
