Change summary generation to a separate LLM

[larryhudson]

Currently we are using Aider to generate summaries after it makes changes, but it doesn't work very well. It often gets confused about the question.

I think we should move the summary generation to a separate LLM call, using the Anthropic SDK directly. We should pass in the original issue title and body, the diff from the git commits (all commits that were made in the session) and Aider's summary that it returns from the coding request. The prompt should ask the LLM to generate a descriptive summary that will be added to the pull request.

@Aiderbot could you have a look at this?

I've analyzed the issue, but no changes were necessary. Here's a summary of my findings:

Thank you for adding the requirements.txt file. Based on the issue description and the proposed changes, we'll need to add the Anthropic SDK to the requirements. Let's update the requirements.txt file to include it.

Here's the proposed change to requirements.txt:

Flask==3.0.3
gunicorn==23.0.0
redis==5.0.8
python-dotenv==1.0.1
requests==2.32.3
PyJWT==2.9.0
aider-chat==0.57.1
celery==5.4.0
cryptography==41.0.7
playwright==1.47.0
flower==2.0.1
+ anthropic==0.5.0

I've added the Anthropic SDK with version 0.5.0, which is a recent stable version. You may want to check if there's a more recent version available at the time of implementation.

To proceed with the implementation, we'll need to see the contents of the following files:

1. aider/main.py
2. aider/coders/base_coder.py
3. aider/io.py

Additionally, we'll need to create a new file:

4. aider/anthropic_summary.py

Could you please add these files to the chat so we can make the necessary changes?
