New logbuffer.py captures app messages (log()) and library logs (faster-whisper, huggingface_hub) into a ring buffer, mirrored to stderr. Settings gains a Log tab: monospace view, 1s refresh, auto-scroll, Copy, Clear — so model download/load progress is visible instead of an opaque "Loading…". transcribe and daemon now log via the buffer.
