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.
Introduced `GetActiveDir` and `CleanActiveDir` methods in the blob store to manage a dedicated directory for active snapshot operations. This ensures a clean working state before starting new operations and prevents conflicts. Updated related logic in snapshot creation and restoration to utilize the active directory.
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.
