Daily plan fixes, task connections, and mobile scroll

A lot of this release is about things that should have just worked. Replanning your day and losing task links. Blocks landing in time slots that had already passed. Closed tasks showing back up in the Open tab. We went through the daily plan flow end-to-end and fixed the rough edges.

Daily plan

• Completed timeboxes now show up in the preview before you apply a new plan, so you can see what's already done.
• Past timeboxes are protected when you apply a plan. Work you've already placed won't get overwritten.
• The schedule won't suggest start times that have already passed.
• All-day calendar events are now included when generating your plan.

Task connections

• Tasks linked to a timebox stay connected after replanning. The link no longer disappears when the schedule is rebuilt.
• When you apply a plan, tasks inside timeboxes are immediately marked as scheduled.
• Closing out your day automatically closes tasks that were inside completed timeboxes.

Suggestions

• Suggestions are now more tailored to how you actually work.

Bug fixes

• Fixed a scroll issue on mobile where the task list would get stuck and couldn't scroll up.
• Fixed closed tasks briefly reappearing in the Open tab after ending the day.
• Fixed a layout issue where a long goal name caused the task detail panel to scroll sideways.
