Feat/errors trace view

[preet-bhadra]

[!IMPORTANT] Add asynchronous crawling to FirecrawlCrawlNode and integrate task data display in the frontend for error trace view.

• Backend:
  • firecrawl_crawl.py: Add asynchronous crawling with async_crawl_url and polling for completion using exponential backoff.
  • node_types.py: Comment out FirecrawlCrawlNode from SUPPORTED_NODE_TYPES.
• Frontend:
  • RunViewFlowCanvas.tsx: Add tasksData prop to update node data with task outputs and errors.
  • trace/[id].tsx: Fetch and pass tasksData to RunViewFlowCanvas for rendering.
