What's needed?

It would be good to add copilot and other AI agents instructions to make life of AI agents users even easier, and to make sure the code is shaped as close as possible to what the project expects.

Proposed solution

Create a AGENTS.md file in the repository template.

Here is a good example from Home Assistant, which matches quite closely our style, so it might be easy to adapt:

• https://github.com/home-assistant/core/blob/dev/.github/copilot-instructions.md
