fix(autostart): run from repo root + visible console at logon

Browse Source 
autostart-run.bat did 'cd /d %~dp0' -> scripts/, but web-vnc.exe/webvnc.conf/
go.mod live in the repo root, so the binary was never found and web-vnc never
started after reboot. Now it cd's to %~dp0.. (repo root).

The task was ONSTART/RU SYSTEM (session 0) so it could not show a window, making
failures invisible. install-autostart.bat now registers ONLOGON /RL HIGHEST as the
current user -> a visible console opens at logon. autostart-run.bat sets a window
title, prints status, stays open while web-vnc serves, and pauses on fatal errors
(no binary / no webvnc.conf) so the reason is visible. Docs updated.

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, WAITS for the VNC server
REM on 127.0.0.1:5900 (the UltraVNC service may still be starting
REM at boot), and only then starts web-vnc.exe in the foreground.
REM If no VNC server comes up, it spawns a local one (portable
REM vnc\winvnc.exe / tvnserver.exe, or auto-detected) so web-vnc
REM does not serve before the VNC server is ready.
REM autostart-run.bat - launcher used by the scheduled task
REM created by install-autostart.bat. Runs in a VISIBLE console
REM window (install-autostart.bat registers it at logon, as the
REM current user, so the window is visible - unlike a hidden
REM SYSTEM/boot task). It reads the password from webvnc.conf,
REM WAITS for the VNC server on 127.0.0.1:5900 (the UltraVNC
REM service may still be starting), and only then starts
REM web-vnc.exe in the foreground. If no VNC server comes up,
REM it spawns a local one. On any fatal error it pauses so the
REM window stays open and you can read why it did not start.
REM
REM This script lives in scripts/ but operates relative to the
REM REPO ROOT (web-vnc.exe, webvnc.conf, vnc\, ./cmd/web-vnc are
REM there), so it cd's to %~dp0.. first.
REM Exit codes: 0 = server ran and stopped; 1 = no binary;
REM 2 = password not configured; other = web-vnc error.
