#1201

This PR adds a new dora topic info command that provides detailed metadata and real-time statistics about dataflow topics/outputs, making it easier to monitor and debug running dataflows.

The new command gives you a comprehensive view of any topic in your dataflow:

  • Data Type: Shows the Arrow data type being transmitted (e.g., UInt64, String, List)
  • Publisher: Displays which node is publishing, along with its real-time frequency in Hz
  • Subscribers: Lists all downstream nodes consuming this topic
  • Statistics: Shows total message count and bandwidth usage over a configurable time window
