Replaces always-on xfreerdp with on-demand model (load 12 to under 1 at idle).
- rdp-proxy/manager.py: HTTP server port 7001 managing xfreerdp lifecycle
- rdp-proxy/entrypoint.sh: starts Xvfb+x11vnc+websockify+manager, no auto-connect
- rdp-proxy/Dockerfile: adds python3, copies manager.py, exposes 7001
- runtime.py: connect_rdp_slot and disconnect_rdp_slot via manager HTTP API
- terminate_session_record: disconnect instead of container restart
- main.py: calls connect_rdp_slot in background thread on session create
- maintenance.py: cleanup_loop disconnects on expire, run_maintenance_service
includes RDP slot init, maintenance_runner fixed to import maintenance
- universal-runtime: set _state[profile_dir] AFTER _start_process so
_stop_current does not delete the freshly-created profile before
Chromium reads it. Without this, Login Data was being wiped.
- rdp-proxy: add xdotool dependency and background anti_idle_loop that
sends Shift to the xfreerdp window every 30s, forwarded over RDP to
reset the remote idle timer and keep the lock screen from kicking in.
