Use model_copy() instead of creating new AIMessage to preserve
response_metadata, id, usage_metadata, etc. Also adds test coverage
for malformed thinking tags pattern.

Add thinking content cleaning to notebook and source chat graphs.
Previously, models that output <think>...</think> tags (like DeepSeek)
or malformed variants without opening tags (like Nemotron) would leak
reasoning content into user-visible responses.
Changes:
- chat.py: Clean AI response content before returning messages
- source_chat.py: Same fix for source-specific chat
- text_utils.py: Handle malformed output where opening <think> tag
is missing but </think> is present
