YDB Temporal support.

We would like to thank the Temporal developers very much for their hard work in creating and maintaining this amazing framework. The contribution of the Temporal team to the development of tools for the development of long-lived applications is incredibly important for many developers and represents a truly valuable resource in modern software development.

Due to the growing demand for the use of Yandex Database (YDB) in modern applications with high requirements for scalability and fault tolerance, we consider it important to add YDB support to the Temporary framework. Temporary is a powerful tool for developing long-lived applications, but currently the lack of native integration with YDB limits the capabilities of developers and reduces the competitiveness of the framework.

Functionality Details:

1. Support for Yandex Database as a repository for Temporary, which will allow developers to take full advantage of the features provided by YDB, such as geographic data replication, automatic scaling and high fault tolerance.
2. Integration of YDB functionality with the Temporary SDK to ensure ease of use and compatibility with existing applications.

Advantages:

1. Expanding the potential audience of Temporary by YDB users interested in developing long-lived applications.
2. Improved performance and scalability of applications using Temporary in combination with YDB.
3. Increasing the competitiveness of Temporal in the market of long-lived application development tools.

This extension of Temporal functionality will enable developers to take full advantage of the benefits provided by YDB in their long-lived applications, which will make Temporal an even more attractive development tool.

The issue requests native YDB repository support and integration with the Temporal SDK, but names no files, tests, or entry points. Start by identifying the repository and SDK components responsible for persistence and reviewing YDB integration requirements. Done would mean documented, compatible YDB support for existing Temporal applications.
