CVE-2025-13353: gokey allows secret recovery from a seed file without the master password

In gokey versions <0.2.0, a flaw in the seed decryption logic resulted in passwords incorrectly being derived solely from the initial vector and the AES-GCM authentication tag of the key seed.

This issue has been fixed in gokey version 0.2.0. This is a breaking change. The fix has invalidated any passwords/secrets that were derived from the seed file (using the -s option). Even if the input seed file stays the same, version 0.2.0 gokey will generate different secrets.
