Convert the .bat scripts from Russian (UTF-8 with BOM + chcp 65001) to plain
English ASCII without BOM/chcp, so they render correctly under any OEM console
codepage without relying on BOM handling.
UTF-8 without BOM + chcp 65001 showed '????' because cmd reads .bat under the
OEM codepage, not chcp. A UTF-8 BOM makes cmd read the file as UTF-8 regardless
of the console codepage; verified Cyrillic in echo/set/for displays correctly
even when cmd starts at cp866. AGENTS.md updated accordingly.
- run.bat / open-firewall.bat: UTF-8 (no BOM) + chcp 65001 instead of cp866/chcp 866.
- scripts/set-vnc-password.bat: removed (run.bat syncs the UltraVNC password via ensure-vnc-password.ps1).
- scripts/ensure-vnc-password.ps1: use a real RFB VNC-Auth probe to 127.0.0.1:5900
to decide if the password already matches (no UAC when it does); set via
createpassword/setpasswd + service restart only when it differs. Works for
any password length (no stored-password encoding assumptions).
- AGENTS.md: .bat encoding convention updated to UTF-8/chcp 65001; drop set-vnc-password refs.
