autostart-run.bat checked 5900 once at startup; at boot the UltraVNC service may not be up yet, so web-vnc either spawned a 2nd VNC server (conflict) or started serving on :8080 before the VNC server was ready, breaking browser connections. Now autostart-run.bat polls 127.0.0.1:5900 for up to ~30s (one PowerShell loop: TcpClient + Start-Sleep 1, exits on first accepted connection) and only then launches web-vnc.exe -- without --spawn when 5900 already listens, or spawning a local server (portable vnc\winvnc.exe / tvnserver.exe, else auto-detect) if it never came up. Docs (AGENTS.md, README.md) updated.
