- upscale.py: add InstallStatus dataclass + ensure_ncnn_installed() async function that downloads and extracts the NCNN binary for the current platform (Linux/macOS/Windows), tracks progress (0-100%), and busts the caps cache when done - main.py: trigger ensure_ncnn_installed() as a background task on app startup when no AI upscaler is detected - print_tools.py: /upscale/available triggers install task when no AI upscaler found; new GET /upscale/install-status endpoint for polling - upscale.js: if no AI upscaler on open, poll install-status showing a progress bar notification, then refresh caps and proceed when done https://claude.ai/code/session_01B58MaJCU1R6KwBDJCp8AfN
