Update autopilot workflow and documentation for project cycle completion

- Modified the existing-code workflow to automatically loop back to New Task after project completion without user confirmation.
- Updated the autopilot state to reflect the current step as `done` and status as `completed`.
- Clarified the deployment status report by specifying non-deployed services and their purposes.

These changes enhance the automation of task management and improve documentation clarity.
