Board view for roadmap

Summary Add a Kanban-style Board view for the roadmap to let product teams visualize status and move items between columns. Problem Our current roadmap is a list. Product teams need a kanban-style board to visualize status and quickly move items between stages during planning. Proposed solution Add a Board (Kanban) view on the roadmap with columns for statuses (default: Backlog, Planned, In Progress, Shipped). Include drag-and-drop to change status and order, quick-edit directly from cards, and the ability to apply filters. Why it matters Better visualization and easier planning during weekly planning sessions—reduces friction when triaging and prioritizing roadmap items. Acceptance criteria Board view available as an alternate view on the roadmap page Columns map to statuses and are configurable Drag-and-drop updates item status and ordering Supports filters and quick edit from cards Priority: High
