The transfer ending is not the dialog's work ending. The checksum still has
to run and the engine still has to load the file, seconds of it on a large
model, and until now that window showed a bar parked at 100% with the
downloader's "Complete!" under it and Cancel as the only button. It reads as
a finished download waiting to be confirmed, or as a hang, and the one
button on offer is the opposite of what the user wants to press.
- ModelDownloadDialog: a fraction of 1.0 no longer paints a finished-looking
bar. It bounces the bar, names the step, says the download is done but the
work is not, and greys out the Cancel button, which cannot interrupt
verification or a model load anyway. Only set_complete() says "Complete!"
and offers OK.
- whisper.cpp: report "Verifying model..." before hashing a file that can be
hundreds of megabytes, the same step the Vosk path has always reported, and
"Loading model..." before backend detection and the load. The tray's
download notification reads the same statuses.
- tests: add return annotations on the new finishing-feedback helpers and
tests (Greptile P2).
