feat: add optional export of thinking/reasoning process

Add a new "Export Thinking Process" setting that includes the model's thinking/reasoning content in Markdown and HTML exports. Supports multiple thinking formats across model generations (gpt-5-2, gpt-5-4, gpt-5-5) including thought content, search activities, and duration.
