This PR adds Docker Model Runner as supported platform to host and run models.

I base it on LmStudio bridge as it works similarly.

DMR docs:

• Getting Started https://docs.docker.com/ai/model-runner/get-started/
• API Reference https://docs.docker.com/ai/model-runner/api-reference/

Examples output:

Consider this first implementation as basic bridge for basic usage. It could be improved during the hackathon by:

• Adding examples (tool calling, image, etc)
• Add guard about model presence (using "Get model" endpoint https://docs.docker.com/ai/model-runner/api-reference/#available-dmr-endpoints) to avoid calling a non-present model

[welcoMattic]

Note

PHPStan failure is expected as example code use not yet merged Bridge in Platform package.

oh, that's due to #535 and not using the components from the branch but via composer install, right?

Indeed, I'll take a look.

I feel like this can be easily fixed with 93464f6

But I get a infinite loop

I assume it's because of #527 cc @chr-hertel

Not sure if we can do something until...

[VincentLanglet]

I'm getting something working #568

proof #552

still unable to install and test locally - sorry - can someone else test and confirm?

What do you need to be able to test? More doc about setting up Docker Model Runner?

Good to merge after my comment, it works seamlessly on my Mac

I forgot to install one model and ended up with:

If possible, it would be nice to throw a MissingModelException, if we can check that beforehand. Can be a follow up PR

Thanks Mathieu for working on this feature, this is much appreciated.
