Resolve conflicts in ask.py and chat.py by merging the try/except error handling from main with the extract_text_content helper from the PR. Also apply the same fix to source_chat.py and transformation.py which had the same vulnerable isinstance/str() pattern for structured LLM response content (e.g. Gemini's envelope format).
