fix(executor): handle exceptions in ShireDefaultLlmExecutor #60

Previously, the ShireDefaultLlmExecutor did not handle exceptions which could lead to unhandled errors during the execution. This commit wraps the LlmProvider streaming process with a try-catch block to print error messages and detach the process in case of exceptions. This ensures a more robust and user-friendly error handling within the executor.
