android-emulator: GPU rendering on node1 + scale-to-zero wake gate

Browse source 
Viktor's direction (2026-06-12): the emulator is dev-only, so it should
be on-demand, and it should use the T4 where applicable. (1) api36-v5
runs '-gpu host' on the GPU node (nodeSelector + time-slice + EGL libs;
automatic swiftshader fallback if GPU init dies) — screen-on rendering
moves off the CPU (~5 cores → expected 1-2). (2) The wake gate (stdlib
python, owns / on both hostnames) scales the deployment 0→1 on visit and
hands the browser to noVNC when ready; agents GET /wake + /status. The
idle-sleeper CronJob counts established adb/noVNC connections via
/proc/net/tcp (excluding the in-container loopback adb client) and scales
to zero after 4 idle checks (~1h). TF ignores replicas drift. VRAM cost
(~0.5-1GiB) is held only while awake, protecting llama-swap headroom.
