add a test to validate important scenarios.

I noticed that the checkpw method in com.hellokaton.blade.kit.BCrypt is not fully tested. Specifically, the current test suite does not cover the branch if (hashed_bytes.length != try_bytes.length), which handles scenarios where the stored password hashes may be corrupted. These scenarios are important to consider, as real-world issues—often introduced during database migrations or system updates—can lead to such inconsistencies.

To address this gap, I’ve added a test that explicitly validates this scenario. I hope it proves helpful in detecting potential regressions.

If additional test coverage would be valuable, I’d be happy to contribute further by looking into other classes you consider important for a follow-up PR.
