Previously readSidecar/writeSidecar were keyed on (path, file_size) with
staleness rejected at read time. Switch to pure path-stem keying: foo.ifc
and foo.ifcdb/ both resolve to foo.ifcview, so the same cache serves either
source format. Staleness is user-managed (delete the sidecar to force a
rebuild), which also lets sidecars be copied or moved independently of the
source.
v8 header drops the source_file_size field.

Handle streamer success, failure, and cancellation as distinct terminal states so failed or cancelled loads do not finalize as successful models. Clean up partial model/UI state in the full and minimal viewer apps when a load is cancelled or fails.
Generated with the assistance of an AI coding tool.
MainWindow and MinimalWindow each carried ~150 lines of mirrored
load-queue, sidecar-thread, streamer-wiring, and ID-rebase code. Lift
all of it into a SceneLoader QObject in the library; both apps now
consume it via signals. Sidecar writes stay on the full-app side since
they need the consumer's element metadata strings.
