fix: 05_inference — kill stale demo.py + background poll exit viser + offload_to_cpu from yaml

- kill_stale_demo_py() before each segment to prevent GPU contention from orphan processes
- Remote script runs demo.py in background via nohup, polls for PLY file every 30s, kills viser server once PLY written — prevents indefinite SSH block on viser listener
- offload_to_cpu now read from thresholds.yaml[inference] (default false for 24GB VRAM)
- timeout reads inference_timeout_s from yaml (already 10800s)
- min_frames guard included (from fix/05-inference-min-frames-timeout)

Root cause: demo.py starts viser server after writing PLY; SSH timed out → orphan; two orphans competed for GPU with offload_to_cpu → pure CPU inference = 6h+ for 493 frames
