Total Tokki 0.4.0 Alpha 79 - Windows installer

1. Double-click install-total-tokki.cmd.
2. Downloads verified split files from the official Cloudflare Pages download site.
3. New installation uses Downloads\Total-Tokki. Existing installations update in their current folder.
4. If multiple older folders exist, choose the path with the profiles you want. Data is never merged automatically.
5. Profiles, reading progress, library, settings, downloads and reader assets stay in their existing locations.
6. App-only backups (two) and an interrupted-update journal allow retry and rollback. Rerun the installer in the same folder after interruption.
7. The tray starts after the basic server passes its health check. TVRoom browser dependencies prepare on first use in the final path.
8. Windows startup keeps your previous choice. Enable or disable it explicitly in the tray menu.
