Introduces core functionality for the Agate library, including snapshot creation, restoration, listing, and deletion. Adds examples for basic usage, gRPC proto definitions, and build/configuration files such as `go.mod` and `Makefile`. The implementation establishes the framework for store integration and placeholder server functionality.
