Policy for AI Coding Assistants

[Hauke Mehrtens]

Hi,

I think OpenWrt does not have a policy regarding AI Coding Assistants. I 
started using them and I always mentioned it in the commit message.

I am pretty sure others used them too on code contributed to OpenWrt.

I would like to take over the policy from the Linux kernel regarding AI 
Coding Assistants:
https://docs.kernel.org/process/coding-assistants.html

I would like to use these rules for OpenWrt:
  * AI Coding Assistants are tools and can be used
  * The contributor takes full responsibility for the code generated
  * The contributor must understand what the code does
  * It should be mentioned when such tools were used
  * The AI should not automatically create PRs, the AI could help a 
person doing this.
