🐛 fix(chat.py): change BuildStatus.IN_PROGRESS to BuildStatus.STARTED for better clarity

🐛 fix(chat.py): fix incorrect key used to retrieve graph_data from flow_data_store
The BuildStatus.IN_PROGRESS constant is changed to BuildStatus.STARTED to provide a more accurate representation of the flow status. Additionally, the incorrect key "data" is replaced with "graph_data" when retrieving the graph data from the flow_data_store dictionary.
