Research direction

Start by reproducing both commands with the reported blockchain.wallet.json input and read blockchain2john.py, focusing on how it detects wallet versions and handles the --json option. Done means the script accepts the reported JSON wallet format without issuing contradictory option guidance; no test file is named in the issue.
