Missing logs from whisper/ggml

[thewh1teagle]

Many important logs from whisper/ggml are missing. for instance when vulkan init failed, due to out of memory issues or similar.
It shows them in stderr but It doesn't get captured in log/tracing.

Maybe we're missing another callback we should register to catch more logs? eg. from ggml?

For instance in the following issue:
thewh1teagle/vibe#360
I had to run it from the terminal to see stderr from whisper.cpp / ggml and only then I understood that it's due to memory issue.
