fix: run k3s as root, bump HPA CPU threshold to 80%

k3s needs CAP_SYS_ADMIN to create network namespaces and mount cgroups.
USER landing was preventing this. Cloud Run gen2 is the security boundary.

60% CPU was too conservative for soul-demo — it is I/O-bound (LLM API calls),
not CPU-bound. 80% gives correct headroom before scaling kicks in.
