fix: add trailing newlines to deterministic commit content

The CommitVariant::file_content() methods were returning strings without
trailing newlines, but the expected hash constants were calculated with
trailing newlines. This caused hash mismatches in tests.

Updated all hash constants to match the actual commit hashes produced
with trailing newlines in the file content.
