Subject: [PATCH] test: verify verify_checksum behavior when file is missing

Added a new test case `test_verify_checksum_missing` to `src/tests/test_checksum_utils.py` to ensure that `verify_checksum` correctly raises `FileNotFoundError` and logs an appropriate error message when the checksum file does not exist. This improves diagnostic reliability for checksum verification failures.
