Big builds go one finished part at a time

When you ask the agent for a big build - a whole app, or everything at once - it now builds the most important part first, shows it to you working, and tells you how many credits that part used. You choose how far to go from there.

• No more guesses. The agent no longer quotes a starting price for work it has not done. No one can price software before it is built, and the low "starts at" numbers often fell far short of the real cost. What a finished part used is a real number, and the best guide to the rest.
• Finished parts first. When your credits can't cover several parts at once, the agent's background tasks run one after another. The credits you have end in parts that work, not in several half-built ones.
• A pause you control. A background task pauses at its Task budget (150 credits by default) with everything it built saved, and goes on only when you say so. On a paid plan you can change the budget in Settings > Billing & plans.
• Out of credits mid-task? The task says so and keeps everything it built. After a top-up, the agent picks it up from where it stopped.
