Background MI50 work was invisible — the dream loop logs one line per cycle, so a
multi-minute consolidation or a chat-on-mi50 showed nothing while the GPU pegged.
Now complete/chat_call/chat_call_stream each emit 'llm call' (kind, backend, model,
~tokens) and 'llm done' (ms, output size, tools). Watch what's hitting any backend
live via journalctl --user -fu lyra-dream -u lyra-web. No signature change, so
test stubs that replace complete() are unaffected.
