feat: Add project structure for 21st Century Skills VLM Model

[ravencore06]

HI @manua-glitch ,
In this PR, I've set up the initial directory structure and dependencies for the VLM Evaluation Pipeline to clearly separate it from the existing Voice AI system.

#2
Moving forward, my planned contributions for this project include:

1. Building the data preparation scripts to format the student artifacts and rubrics.
2. Developing the LoRA fine-tuning pipeline for an open-source VLM (like Qwen-VL or LLaVA).
3. Creating the benchmarking and cost-evaluation scripts to ensure we achieve the < ₹0.10 target.

Looking forward to your feedback on this initial setup!

Changes Made for Initial contribution:

• Documentation: Updated the main README.md to clearly define the two distinct AI initiatives within this repository.
• Project Structure: Created the vlm_evaluation/ directory to house all VLM-related data, scripts, and model evaluations.
• Dependencies: Added vlm_evaluation/requirements.txt containing the necessary ML packages (transformers, torch, peft, bitsandbytes, Pillow, accelerate, datasets) required for upcoming VLM fine-tuning and inference tasks.
