See what a chat has spent, right in the chat picker

Every chat now carries its own receipt. Open the chat picker in the editor (click the chat name above the conversation) and the bottom of the menu shows two quiet numbers for the current chat:

• Spent in this chat - the total AI credits this conversation has used so far.
• Context - how much of the model's working memory the chat is filling.

When a chat runs long, the context number turns amber with a tip: long chats reply slower and cost more, so starting a new chat for the next task keeps you fast and cheap.

Nothing ticks while the AI works - the receipt only appears when you ask for it.
