- universal-runtime: set _state[profile_dir] AFTER _start_process so
_stop_current does not delete the freshly-created profile before

- 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.
