snider bd7e8b3040 feat: lazy loading profile page + v3 streaming polish
Profile page:
   - No WASM or video download until play button clicked
   - Play button visible immediately, loading on-demand
   - Removed auto-play behavior completely

   Streaming:
   - GetV3HeaderFromPrefix for parsing from partial data
   - v3 demo file with 128KB chunks for streaming tests
