CDN-Based Network Streaming for HoloTensor Fragments
This module implements intelligent network streaming for loading model fragments from CDN/edge locations with:
- Range Requests: Partial downloads for progressive loading
- Parallel Fetching: Concurrent chunk downloads
- Smart Caching: ETag/Last-Modified validation
- Retry with Backoff: Resilient to transient failures
- Priority Queue: Critical fragments first
- Bandwidth Adaptation: Adjusts to network conditions
