google-genai >=1.70 changed Part.from_text() from positional to
keyword-only argument. The production container installed v1.73.1
and crashed on startup with "Part.from_text() takes 1 positional
argument but 2 were given".
Fix: Part.from_text(msg.content) → Part.from_text(text=msg.content)
Tested live: curl https://llm.mana.how/v1/chat/completions with
model=google/gemini-2.5-flash returns correct response.
