mudler's LocalAI [bot] 90d93c71cd fix(downloader): hash the partial file before issuing the resume request (#11099)
The stall watchdog arms as soon as the response body exists, but the
downloader then re-hashed the entire existing .partial before reading a
single byte from the network. On slow models storage (a CIFS share
reading at ~117MB/s) hashing a multi-GB partial outlasts the 60s stall
window, so the watchdog aborted every healthy resume with 'download
stalled: no data received for 1m0s'. The partial never grew, so every
retry re-paid the same hash and failed identically, wedging the install
permanently (any partial over ~7GB on such storage).

Open the partial and hash it before the HTTP request instead: the
watchdog now only measures actual network idle time, and the origin no
longer sits on an idle connection while the hash runs.
