Summary:

Added detailed task information including steps, actions, and cost to the task page and refactored components to use a new TaskInfo component.

Key points:

• Updated skyvern-frontend/cloud/routes/billing/TaskCost.tsx to exclude running steps from cost calculation.
• Refactored skyvern-frontend/src/routes/tasks/detail/StepArtifactsLayout.tsx and StepNavigation.tsx to handle cases where steps might be undefined.
• Introduced TaskInfo component in skyvern-frontend/src/routes/tasks/detail/TaskInfo.tsx to display task status, steps, actions, and cost.
• Updated skyvern-frontend/src/routes/tasks/detail/TaskDetails.tsx to use the new TaskInfo component.
• Added useTaskQuery hook in skyvern-frontend/src/routes/tasks/detail/hooks/useTaskQuery.ts for fetching task data.
