Add pipeline tag and improve model card

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

This PR improves the model card for SAMA-14B by:
- Adding the `image-to-video` pipeline tag to the metadata for better discoverability.
- Including a "Quick Start" section with installation and inference instructions taken from the official GitHub repository.
- Organizing the content to include helpful links to the paper, project page, and code.

These changes help users understand how to set up and run the model effectively.

+SAMA (factorized **S**emantic **A**nchoring and **M**otion **A**lignment) is an instruction-guided video editing framework. It factorizes video editing into two parts: semantic anchoring to establish structural planning and motion alignment to internalize temporal dynamics. This approach enables precise semantic modifications while faithfully preserving the original motion of the source video.
+
+## 🚀 Quick Start
+
+### 🛠️ Installation
+
+Recommended environment: Linux, NVIDIA GPU, CUDA 12.1, and Python 3.10.
+
+```bash
+git clone https://github.com/Cynthiazxy123/SAMA
+cd SAMA
+
+conda create -n sama python=3.10 -y
+conda activate sama
 
+pip install --upgrade pip
+pip install -r requirements.txt
+```
+
+### ▶️ Inference
+
+To run instruction-guided video editing, you will need the base `Wan2.1-T2V-14B` model and the SAMA checkpoint. 
+
+The inference script is located at `infer_sh/run_sama.sh`. Edit the variables at the top of that script (such as `MODEL_ROOT`, `STATE_DICT`, `SRC_VIDEO`, and `PROMPT`) and then run:
+
+```bash
+bash infer_sh/run_sama.sh
+```
