updates to containerization

Containerization!

[Copilot]

Pull request overview

This PR adds containerization support for KernelPort with separate CPU and GPU Docker images, updates the gRPC API to use proper protobuf enums for data types, and implements a model fetching mechanism for HuggingFace.

Changes:

• Added Docker support with CPU (Dockerfile.cpu) and GPU (Dockerfile.gpu) images, including a model fetch script and entrypoint
• Updated gRPC API from Predict to Infer with proper DType enum instead of string-based types
• Added documentation for model ingestion, validation, and manifest schema
