Add Monthly, Quarterly & Yearly Views to Timeline for Better Long-Term Planning

Currently, the timeline view works great for day-to-day and weekly planning, but it lacks broader time horizon perspectives that are essential for effective long-term planning.

It would be useful to have the ability to switch between different timeline views:

• Monthly View – See all tasks and goals laid out across the entire month

• Quarterly View – For quarterly planning

• Yearly View – Get a bird's-eye view of your annual goals

Some apps have explored similar concepts (like horizon-based planning in timestripe)
