Brandon ThomasandClaude Opus 5.5 1a6a9de7ee Issue #33: Devices: serve the cached card list and rescan in the background
Menus are rebuilt every frame, and File → Add from Device called
devices(), which scanned every mount (D:..Z: on Windows) while holding
the cache mutex once its 2 s cache expired. devices() now returns the
last scan at once and starts at most one background rescan when it is
stale; the scan runs without the lock. A changed result calls an
on_change hook (the UI requests a repaint), so hot-plugged cards still
appear. library.devices and Add from Device without a path scan
synchronously (devices_now). Volume roots are probed for DCIM directly
instead of listing them (Windows never lists a root). No threads or
clock on wasm.
