GKE AI Troubleshooting TPU Vbar OOM

The skill diagnoses and prevents vbar_control_agent segfaults, out-of-memory errors, and TPU device initialization failures on TPU v6e nodes in GKE caused by race conditions during device resets or high-frequency metrics polling. It is used when troubleshooting vbar_control_agent crashes, memory cgroup OOMs in serial console logs, tpu-device-plugin metrics checksum corruption, or custom TPU metrics collection conflicts on GKE TPU v6e nodes. It is not intended for general non-TPU container OOM troubleshooting or standard GKE node lifecycle operations.
