LR-IMP-DEVICE: import from camera / memory card

library.devices lists mounted volumes with a DCIM folder (macOS /Volumes, Linux /media and
/run/media, Windows drive letters; LIGHTCRAFT_DEVICE_ROOTS overrides; cached for 2 s).
File → Add from Device opens the import review of a card's DCIM folder, set to copy into the
library.
