[Feature Request]: Compatibility with Chainner

Nobody has claimed this yet.

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

Chainner ([https://github.com/chaiNNer-org/chaiNNer](url)) is a node processing gui that allows complex workflows and can be linked with A1111 to perform certain steps. However, SD forge API must be somewhat different since chainner manages to detect it; but not to obtain a valid response.
I made the same request in chainner ([https://github.com/chaiNNer-org/chaiNNer/issues/2839](url) but when asked about the API, I couldn't answer anything since I am not an expert.
I think compatibility can be achieved with minimal effort in this case since it is only a miscomunication between both programs.

If someone with the know-how about the SD forge API can post in the chainner issue, it could help bring this feature to light in future versions.

### Proposed workflow

1. Open chainner and SD forge
2. Chainner detects SD-forge correctly
3. SD-forge can be added to workflows

### Additional information

_No response_

Start by reading the linked Chainner issue #2839 and comparing Chainner's expected API behavior with SD Forge's API responses. The work is done when Chainner detects SD Forge, accepts it in workflows, and completes the proposed workflow successfully.
