This is missing a sdcpp_logger_adapter cleanup; it's not clear to me if that module would still be useful.

tbh we can get rid of it but if we do so we just have to patch the native sd logger for the string format reasons i mentioned earlier in discord

Sent it upstream: leejet/stable-diffusion.cpp#2002

But there is also the threading issue: log_printf uses a static buffer. That's not exactly comfortable for ggml logs.
