Code Review

This pull request introduces the list_tasks functionality, allowing clients to retrieve a paginated and filterable list of tasks. The changes are extensive and well-implemented across the entire stack, including client interfaces, transports (gRPC, JSON-RPC, REST), server-side handlers, and data stores (in-memory and database). The new database query for listing tasks includes robust keyset pagination, which is excellent for performance. The test coverage for the new feature is thorough, with unit, integration, and parameterized tests ensuring correctness and consistency. I've found a couple of minor leftover debug print statements that should be removed. Overall, this is a high-quality contribution.
