"""Main window: open a folder of images and inspect what the detector found.
Layout: a toolbar (open folder · from-video · detector · model · calc-frame ·
detect-all · threshold), then a splitter with three panes — left: collection
controls + the file list; center: the image with overlays; right: a detail table
of every detection. Collection controls sit by the file list (they act on its
selection), keeping the toolbar to detection/entry actions only.
Viewing and detecting are decoupled, so browsing a big folder stays instant even
with a slow (CPU) detector:
- selecting a file just **shows** it (with its cached result, if any);
- **double-clicking** a file, or "Рассчитать кадр", runs the detector on it;
- "Детектировать все" runs the whole folder.
Both folder loading and detect-all show a progress bar. Results are cached;
switching detector/model clears the cache.
