Service executable paths in installService.bat and uninstallService.bat now use %APPDATA% for improved portability. The setup.iss installer script updates registry keys to use the application name macro, adjusts file and icon paths to user appdata, and changes PowerShell execution flags. afterInstall.ps1 now downloads and extracts WelsonJS binary artifacts from a remote URL.
Introduces afterInstall.ps1 for post-install setup, downloading and extracting required tools to the APPDATA\WelsonJS directory. Updates code in http.js, python3.js, ovftool.js, wamr.js, and system.js to reference binaries from the new APPDATA location. Modifies setup.iss to run the PowerShell script after installation.
