This commit introduces test cases for the API, archive, store, and filesystem functionalities, as well as a functional test for a full workflow. It ensures robust testing for snapshot operations, archiving, and blob management, significantly improving reliability.
Updated `SaveSnapshot` and `RestoreSnapshot` methods to reference the active directory via `BlobStore`. Introduced `RestoreSnapshotToDir` for granular restore operations. Additionally, updated dependencies in `go.mod` to their latest versions for compatibility and maintenance.
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.
