Update pipeline tag and improve model description

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

I've opened this PR to refine your model card. The main changes include:
- Updating the `pipeline_tag` to `other`, as this model is a specialized SAT branching policy rather than a general-purpose text generator.
- Adding a brief introduction to the model based on your paper abstract to provide more context.
- Updating the citation to the ICLR 2026 version as found in your GitHub repository.

+## Introduction
+ImitSAT is a branching policy for conflict-driven clause learning (CDCL) solvers based on imitation learning for the Boolean satisfiability problem (SAT). Unlike previous methods that predict instance-level signals, ImitSAT learns from expert **KeyTrace**—a sequence of surviving decisions from a full solver run. This prefix-conditioned supervision enables ImitSAT to reproduce high-quality branches, reducing propagations and wall-clock time.
