Hudra changelog

0.9.0

Removed the startup fade and wordmark so presentations begin immediately.
Added live audience zoom controls from 70% to 150%.
Added audience scroll up/down controls with press-and-hold support.
Added mouse-wheel audience scrolling and Shift + wheel zooming over the current preview.
Added Reset view and live view status.
Kept the product name simply Hudra.
Retained dual-screen presenter view, slide previews, timing, clicker support, audience blanking and video controls.

Added one narrowly scoped feature: slides containing exactly one image now fit that image to the full audience viewport using object-fit: contain.
Landscape images fit to width and portrait images fit to height without cropping or distortion.
All other slide types retain the original Hudra 0.9 behaviour.
