fix(cli): remove redundant 'bytes' suffix from debug paths size output

Fixes bounty issue #1432

The format_bytes function already returns a human-readable format with
appropriate units (B, KB, MB, GB). Appending 'bytes' after it resulted
in inconsistent output like '1.0 KB bytes'. This fix removes the
redundant suffix.
