Brandon ThomasandClaude Opus 5.5 b3249bfb57 Perf: cache the photo grid's layout — 43 → 5 ms per frame at 100k photos ...

The justified layout (and the aspect ratio of every photo it needs) was rebuilt every frame.
It is now kept in LightcraftApp::caches, keyed by catalog revision, the photos in view, the
width, the thumbnail size, the mode and the date groups. Headless measurement (ignored test
grid_frame_100k, machine under load): 43.1 → 5.3 ms on the UI thread.
