Build without a second click

Auto builds when you ask for a change, answering a question in Needs You continues the same Build, and follow ups continue from the chat's last result.

What changed

Auto builds when you ask for a change, without a second click.
Answering a question in Needs You continues the same Build.
Follow ups continue from the chat's last result. Nothing reaches your project folder until you Apply.
Plan stays Plan: a Plan follow up revises the active plan, and Build this plan builds that exact version.
