SylphyHornPlus: download ældre versioner

- Added automatic app placement: new windows of registered apps are placed on a desktop specified by number or name.
- Missing desktops can be created (up to 10 at a time).
- Empty desktops can be closed after use.
- Already open windows can be rearranged.
- Added wallpapers for new desktops, set by desktop name or number.
- Added `sylphyhorn-cli`, a command-line tool to operate the running SylphyHornPlus from scripts and AI agents.
- WinGet installations provide it as the `sylphyhorn-cli` command.
- An agent skill that teaches AI coding assistants how to use it is included in the `skills/sylphyhorn` folder of the application.
- Fixed SylphyHornPlus stopping when the device switches to battery power while started by the scheduled (elevated) startup task (#57).
- Existing tasks are not updated automatically. After updating, disable and re-enable "Automatically start as administrator at logon" to recreate the task.

- Improved responsiveness during virtual desktop switching by moving notification window rendering off the main UI thread.
- Hardened startup after user sign-in by deferring virtual desktop initialization until the Windows shell is ready, then enabling global hooks and the tray UI only after initialization succeeds.
- Prevented clearing a per-desktop wallpaper path from changing the Windows background mode.

- Fixed the WinGet command alias so that `SylphyHornPlus` correctly launches `SylphyHorn.exe` instead of attempting to start `SylphyHorn.dll`.
- Added a small native launcher for x86, x64, and ARM64 WinGet installations.
- Added release-package validation for the launcher, forwarded command-line arguments, executable architecture, and WinGet manifest topology.
- Improved WinGet release automation while preserving the existing release notes during manifest updates.

- Add support for Windows 11 24H2 build 26100.2605 or later.
- Add support for Windows 11 23H2 build 22621.3085 or later.
