Writes the missing Phase 11 (VM creation via Proxmox UI, GPU/Coral/disk
passthrough, Ubuntu install) and Phase 12 (NVIDIA driver, Docker, NVIDIA

walkthrough-phases-10-12.md, then assembles all 12 phases into a single
docs/complete-walkthrough.md with a table of contents and an expanded
troubleshooting section covering guest nvidia-smi failures and ZFS disk-full.
