models.ecosyste.ms - Hugging Face model analysis service

A dedicated service for Hugging Face models, structured like docker.ecosyste.ms: pull the model list from packages.ecosyste.ms (once ecosyste-ms/packages#1595 lands) and do model-specific analysis on top.

Things the HF API exposes that don't fit the packages schema but form a real dependency graph:

- `base_model:` and `base_model:finetune:` tags — which model a fine-tune was derived from
- `dataset:` tags — training data provenance
- `model-index` — eval results and benchmark scores
- `siblings` file list — safetensors/GGUF/ONNX format detection, adapter vs full model
- `config.architectures` — model family grouping
- `gated` / `disabled` status

The fine-tune lineage is the most interesting part. It's effectively a dependency tree across ~2M models that nobody currently surfaces.

Would also cover HF datasets and spaces, which are separate API namespaces (`/api/datasets`, `/api/spaces`) with the same git-backed structure.
