--headless renders the current view straight to a PNG and exits, with no window/event loop: it builds its own offscreen wgpu device and reuses the same reference-orbit + ExportRender path as the "Export PNG" button. --width/--height set the output resolution (default 1920x1080); not yet supported with --buddhabrot. Refactors FractalApp::new's state construction and CLI handling into default_state()/apply_cli() so headless mode can reuse them, and factors the PNG tile-render/readback/encode loop into a shared export_to_png_blocking() used by both the windowed export path and headless.
