REM ============================================================
REM  autostart-run.bat - non-interactive launcher used by the
REM  scheduled task created by install-autostart.bat.
REM  Reads the password from webvnc.conf, finds a LOCAL VNC server
REM  (does NOT download anything), and starts web-vnc.exe in the
REM  foreground. The task keeps the process alive and restarts it
REM  on next boot.
REM  Exit codes: 0 = server ran and stopped; 1 = no binary;
REM              2 = password not configured; other = web-vnc error.
