• Fixed: 8b62c797 Immediate response when snapshot installation is unnecessary; by 张炎泼; 2024-05-05

  When Engine::handle_install_full_snapshot() is called and the provided
  snapshot is not up-to-date, the snapshot should not be installed, and
  the response should be sent back immediately. Previously, the method
  might delay the response unnecessarily, waiting for an installation
  process that would not proceed.

  This commit adjusts the logic so that if the snapshot is recognized as
  outdated, it immediately returns a None Condition, ensuring the
  caller is informed straightaway that no installation will occur.
