Contribute to upstream clients to introduce User-Agent

[lukehinds]

Many of the upstream clients are not setting a UA, which makes it hard for us to know who is connecting.

From a quick check I see:

Cline

User-Agent: axios/1.7.4

Continue

User-Agent: node-fetch

Aider

User-Agent: OpenAI/Python 1.57.0

We should seek to contribute patches upstream to help them set something specific to the client

Subtasks

• Contribute to Aider to set user agent
• Contribute to Cline to set user agent: feat: add cline user agent in Axios requests cline/cline#1420
• Contribute to Continue to set user agent
• Contribute to Kodu to set user agent

Should we create a subtask per client? This way we can get different devs contributing to the clients in parallel

I was looking at aider and it's just using litellm which uses either its own http client implementation that hardcodes the user-agent to litellm or in case of openai, directly the openai client. I'm going to check how much work it would be to patch litellm to be able to pass on the user-agent by the caller.
