feat: add Windows Inno Setup installer

Add a proper .exe installer for Windows using Inno Setup, replacing the
raw .zip extraction. Includes Start Menu shortcut, desktop shortcut option,
uninstaller in Add/Remove Programs, and LZMA2 compression. Also adds a
pre-built icon.ico asset and simplifies install.ps1 to download and run
the setup executable silently.
