Goal

Add lab12 solution — Kata Containers VM-backed sandboxing vs runc runtime comparison.

Changes

• Add labs/submission12.md with full task documentation and analysis
• Add labs/lab12/setup/ — build script + kata-built-version.txt
• Add labs/lab12/scripts/ — containerd config + kata assets installer
• Add labs/lab12/runc/health.txt — juice-runc HTTP 200 evidence
• Add labs/lab12/kata/ — test1.txt, kernel.txt, cpu.txt (Kata run outputs)
• Add labs/lab12/analysis/ — kernel-comparison.txt, cpu-comparison.txt
• Add labs/lab12/isolation/ — dmesg.txt, proc.txt, network.txt, modules.txt
• Add labs/lab12/bench/ — startup.txt, http-latency.txt

Testing

• Manual — ran all tasks on Linux host with hardware VT-x; Kata runtime verified via uname -r showing guest kernel 6.12.47 vs host 6.8.0-52-generic
