smolcluster adds grove for cluster training

Strong infrastructure update with real usability value, especially for people who want local distributed training without babysitting network config.

• –The main win is operational simplicity: no static IPs, SSH config, or manual port wiring for basic cluster formation.
• –grove appears to be the differentiator here, while smolcluster is the training system that benefits from it.
• –The post is technically credible because it matches smolcluster’s existing socket-based, heterogeneous-hardware focus.
• –This is more of a product update than a brand-new product launch, since it extends an existing open-source stack.
• –The downside is that the claim is strongest for small local clusters; it still sounds like serious runs may require more setup.
