Expand org README: community + open-foundations framing

Hi @wjbmattingly — opening as a PR rather than a direct commit since you're co-maintainer and this changes the landing-page framing meaningfully. Veto/edit anything you want.

Current README is the placeholder ("Lightweight AI models for cultural heritage institutions / More coming soon"). With 14 models + 9 datasets in the org now (plus a couple of book chapters explaining the recipes), it felt time to flesh it out.

Changes:
- Kept the hero gif and frontmatter unchanged.
- Replaced the "more coming soon" stub with a landing-page body.
- Framing: the org as a community relay — open foundations + community datasets → small task-specific models → extensible by the next institution. Named YOLO/DETR/BERT/Qwen-VL, BigLAM, and the index-card-detector-v5 extension of NLS's detector as the worked example.
- Linked AI Patterns for GLAM (incl. Boring AI + Beyond Chatbots) for the why.
- CTA: a "share a model, or suggest one" section pointing at Discussions, with the idea of curating contributed models into an org collection.
- Maintainer line names both of us + flags wider community contributions.

Happy to take this in, partially merge, or pass on it.

+Most of what gets done in libraries, archives and museums runs on a long tail of small, repetitive jobs — backlogs to clear, scans to make searchable, metadata to tidy. A good chunk of that work can be handled by small, task-specific models, and the people who know what those tasks are are the people working in those institutions.
+
+This org is a place to put the models that come out of that work, so the next institution facing the same problem doesn't start from scratch.
+
+Each model here builds on something. Most are fine-tunes of open foundation models — YOLO, DETR, BERT, Qwen-VL — trained on community datasets, often from [BigLAM](https://huggingface.co/biglam) or contributed by individual institutions. Several extend existing community-trained models for new collections rather than starting over: [index-card-detector-v5](https://huggingface.co/small-models-for-glam/index-card-detector-v5) takes the National Library of Scotland's archival card detector and extends it to three additional archives. That extension pattern matters — it's how this kind of work gets cheaper for everyone over time.
+
+Recipes for most of the models live in [AI Patterns for GLAM](https://danielvanstrien.xyz/ai-patterns-for-glam/); [The Case for Boring AI](https://danielvanstrien.xyz/ai-patterns-for-glam/discovery/boring-ai.html) and [Beyond Chatbots](https://danielvanstrien.xyz/ai-patterns-for-glam/discovery/beyond-chatbots.html) set out the why.
+
+## How the models get built
+
+Mostly with agentic workflows: an agent handles the data prep, training, and packaging; a human stays in the loop for the parts that matter — label review, evaluation, deciding whether something is good enough to release.
+
+## Share a model, or suggest one
+
+If you've trained a small task-specific model for your own collection, share it in [Discussions](https://huggingface.co/spaces/small-models-for-glam/README/discussions) and we'll add good ones to a curated collection so other institutions can find them. Suggestions for tasks you'd like to see covered are welcome there too.
