Karuzip / DeepSeek Harness synthetic archive fixtures

Extract this package into a new demo directory before launching the agent.
It contains sample.zip, deliberately damaged bad-crc.zip and the original source files.
The damaged sample is expected to fail archive.test.
No executable, credential, personal file or real archive password is included.
Download deepseek-task-en.txt separately and replace <KARUZIP-RUNTIME> with your CLI installation directory.
The recorded task used the Karuzip 2.2.3 development build; public download versions may differ.
