localai-org-maint-botandEttore Di Giacinto 2ba6600440 fix(detection): avoid temporary image files (#11938)
RF-DETR and Locate Anything wrote each decoded request image to the OS
temporary directory. A full temporary filesystem then disabled detection,
even though both native libraries already accept encoded image buffers.

Pass decoded images directly to the native buffer APIs. This removes the
request-time disk dependency and prevents crash-orphaned image files.
