Agent builder: autosaved drafts and persistent Bob conversation history

The Agent Builder now saves your work as you go. When you open an agent to edit it, your changes are captured in a personal draft that autosaves as you work, so you can step away and come back without losing anything. A "saved" indicator shows when your work is stored, and if you try to leave with unpublished changes you'll be prompted first. When you're ready, publish the draft to make it live — or discard it to go back to the published version.

The agent's Bob conversation now stays with the agent itself. The context you built up with Bob while working on an agent persists across sessions, and anyone who opens that agent to edit it can see the prior Bob conversation history — so the working context carries forward instead of starting from scratch each time. We wanted to increase visibility into changes made to the agent through the conversations had with Bob. Within the Bob conversation, the user will also see a notification of things changed to the agent manually — so that all context of changes is visible within the Bob conversation.
