docs: Update documentation for streaming fallback feature

- Add streaming endpoint fallback to README.md features
- Add 'How Downloads Work' section explaining P2P + streaming
- Update QUICKSTART.md with download process examples
- Update CHANGELOG.md with v1.1.0 release notes for streaming fix

The tool now automatically falls back to daemon streaming when P2P
peers are unavailable, ensuring reliable downloads.

+## How Downloads Work
+
+The downloader uses a two-stage approach for maximum reliability:
+
+1. **P2P Attempt**: First tries to download from LBRY's peer-to-peer network
+2. **Streaming Fallback**: If P2P peers are unavailable (common for older content), automatically falls back to the daemon's local streaming endpoint
+
+This ensures content downloads successfully even when the P2P network has no seeders.
