v0.1.0

Sample captures generated with --seed release, two zips per scenario and difficulty:

• <run>-student.zip: capture.pcap, briefing.md (handout) and submission_template.yaml
  (fill it in, then grade it with pcapforge grade answers.json <submission>).
• <run>-instructor.zip: the whole run, including answers.json, siem/ and detections/.
  Keep it away from students.
