      summary: Get Asset Hub Migration information.
      description: Returns information about Asset Hub Migration (AHM) including migration start and end blocks for both relay chain and Asset Hub. The endpoint automatically detects whether you're connected to a relay chain or Asset Hub and provides relevant migration data. Returns static migration boundaries for known networks or queries on-chain migration pallets for dynamic information.
