Feature Request: Add Support for 'think' Tag to Display Processing Time

[victorcomposes]

I would like to propose the implementation of a feature that supports the use of a think tag in the output. This tag should visually indicate the time the model spends "thinking" or processing a request, without displaying the detailed reasoning content until the next interaction turn.

The think tag would improve how users experience things by:

• It would show users that the model is working on their request.
• Creating a more streamlined and focused interaction
• Allowing users to see the time taken for the model to generate a response
• Separating the processing phase from the detailed reasoning phase

Expected Behavior:

1. When the think tag is present in the user's input, the system should:

• It would only show how long it took to process (e.g., "Processed in 2.5 seconds").
• Ensure a smooth transition to the next response

2. If the think tag is missing, the system should work normally and give the full response.
