Live Player - portable build

No installation needed - just double-click LivePlayer.exe.
Your projects/audio cache still live in your normal Windows user
profile (%APPDATA%), not next to this folder, so this exe can be
moved to a USB drive and still work normally on any Windows
machine with the WebView2 Runtime installed (present by default
on any Windows 10/11 kept up to date via Windows Update).

Updates: this portable copy does not update itself. When a new
version is available, Help shows a link to the download page;
replace this folder with the new one. Your license and projects
stay in %APPDATA% and are kept.
