Add timeout parameter to run_in_thread function

This PR adds a new timeout parameter to the run_in_thread function, which allows setting a maximum execution time for the thread. After the specified timeout is exceeded, an asyncio.TimeoutError is raised.

Changes

• Added an optional timeout parameter to run_in_thread
• Updated the implementation to use asyncio.wait_for for handling timeouts
• Added documentation for the new parameter
• Added unit tests for the new functionality

Testing

• Added unit tests for the timeout functionality
• Verified that all existing tests pass
