fix: convert AgentAction to AgentFinish in finalize instead of skipping

Browse Source 
When the flow-based AgentExecutor reaches finalize() with an AgentAction
still in current_answer (e.g. after max iterations or all todos complete),
the previous code returned "skipped" which left invoke() with a non-AgentFinish
answer, raising RuntimeError('Agent execution ended without reaching a final
answer.'). Now we convert the AgentAction to AgentFinish using its result or
text, preventing the crash.
