Subject: [PATCH] Add installer/installer.iss (Inno Setup 6 minimal)

Produces drover-vX.Y.Z-setup.exe via `iscc /DMyAppVersion=X.Y.Z installer/installer.iss`.

- Stable AppId UUID for upgrade compatibility
- Bundles drover.exe, WinDivert.dll/sys, LICENSE, README, WinDivert-LGPL
- English + Russian wizard languages
- Optional desktop icon and Windows autostart tasks
- HKCU registry entry for updater install-path discovery
- Best-effort service stop/uninstall on uninstall
- ARM64 refusal in [Code] InitializeSetup (WinDivert has no ARM64 build)
- Requires admin (kernel driver install), x64-compatible only, Win10 1809+
