Scheduled runs choose their destination · project questions recovered

Scheduled Tasks
- You can now choose where each scheduled run lands: create a fresh task every time, or append the results to one existing task you pick.
- When a schedule creates new tasks, you can now decide whether they go into the schedule's own project or into the automatic aggregation group, so a daily job no longer scatters tasks where you did not expect them.
- Picking an existing task now has a searchable list, so you can find the right one instead of scrolling.
- The execution-target setting moved into a dropdown, and its explanation now appears once instead of repeating on every option.
- Fixed the model picker inside the schedule dialog so it scrolls properly when the list is long.
Projects
- Fixed project suggested questions that could stay stuck on the generic placeholder forever. If summary generation had failed once, the project was permanently skipped afterwards; those projects now recover on their own and show real, project-specific suggestions again.
