Sprint Board

Build and manage a project sprint board on canvas:

1. Check for integrations — If Linear or GitHub is connected, install via connect:
   • connect({ name: "linear" }) to fetch live tasks from the integration
   • Otherwise maintain tasks in the canvas using local state and write_file
2. Define model — Task data shape:
   • title, assignee, priority (High/Medium/Low), status (To Do/In Progress/Done), points
3. Build canvas — Sprint board (write_file canvas TSX):
   • KPIs: open tasks, velocity (pts completed), bugs, completion %
   • Kanban: 3-column grid with task cards showing title, priority badge, assignee, points
   • Burndown Chart: points remaining over time
   • Activity Table: recent task updates
4. Manage — When user says “add task” or “move task”:
   • Update canvas state and re-write the file
   • Status-transition buttons handle changes locally in the canvas component
5. Track — Log sprint progress to memory for velocity calculations
