fix(devins-lang): fix asynchronous execution issue #100

Add atomic reference and use invokeAndWait to ensure proper asynchronous execution, preventing race conditions.

This commit fixes an issue in DevInsProgramRunner where asynchronous execution could result in race conditions. By adding an atomic reference and using invokeAndWait, the asynchronous execution is now handled in a thread-safe manner.
