feat: stream yolo at 4k

virtio-gpu exposes no NVENC/VAAPI, so sunshine software-encodes. Measured
x264 (superfast+zerolatency) on the 8 vCPUs: 73fps at 2160p against 135fps
at 1440p, so a 60fps client keeps roughly 20% margin.

Also brings the drifted agent-of-empires config upstream, which the
mutableFiles guard required before switching.
