Add pipeline tag and improve documentation

Hi! I'm Niels from the community science team at Hugging Face.

I've opened this PR to improve the model card for Shesha:
- Added `pipeline_tag: other` to the metadata to better categorize the repository.
- Included a summary of the Shesha framework and the concept of geometric stability based on your paper "Geometric Stability: The Missing Axis of Representations".
- Added a citation section to help users correctly cite your research.

Please let me know if you have any questions!

 # Shesha: Geometric Stability Metric
 
-This is the official Hugging Face hub for the **Shesha** geometric stability metric, as presented in the paper *Geometric Stability: The Missing Axis of Representations* (arXiv:2601.09173).
+This is the official Hugging Face hub for the **Shesha** geometric stability metric, as presented in the paper [Geometric Stability: The Missing Axis of Representations](https://huggingface.co/papers/2601.09173).
+
+## Overview
+
+Analysis of learned representations typically focuses on *similarity*, measuring how closely embeddings align with external references. However, similarity reveals only what is represented, not whether that structure is robust. 
+
+**Shesha** is a framework for measuring **geometric stability**, a distinct dimension that quantifies how reliably representational geometry holds under perturbation. Across 2,463 configurations in seven domains, research shows that stability and similarity are empirically uncorrelated ($\rho \approx 0.01$). This distinction makes Shesha a necessary complement to similarity for auditing representations across biological and computational systems.

+
+## Key Applications
+
+Geometric stability provides actionable insights across multiple domains:
+- **Safety Monitoring:** Acts as a functional geometric canary to detect structural drift nearly 2$\times$ more sensitively than CKA.
+- **Controllability:** Supervised stability predicts linear steerability with high correlation ($\rho = 0.89$-$0.96$).
+- **Model Selection:** Dissociates from transferability, revealing the "geometric tax" that transfer optimization incurs.
+- **Scientific Analysis:** Predicts CRISPR perturbation coherence and neural-behavioral coupling.
