deploy: bundle pre-built MPP libs for RK3326, update setup script and status
- deploy/arkos/mpp-libs/: add librockchip_mpp.so*, librockchip_vpu.so*,
libgstrockchipmpp.so — built from source via Docker QEMU (arm64v8/ubuntu:focal)
using rockchip-linux/mpp + JeffyCN/mirrors@gstreamer-rockchip (-Drga=disabled)
- deploy/arkos/setup_hw_decode.sh: detect mpp-libs/ subdir and install from it
automatically, no network required; apt fallback retained
- deploy/arkos/mpp-libs/README.md: document origin, target SoC, install steps
- tests/test_video_playback_device.py: on-device GStreamer diagnostic script
- docs/development-status.md: mark MPP HW decode deployed, mppvideodec verified
Verified on physical R36S: mppvideodec found by GStreamer registry with
GST_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/gstreamer-1.0
