* fix(cli): snapshot no longer transcodes every iPhone clip it never plays
snapshot served Studio's media proxies by default, so its page server transcoded every browser-hostile clip (every HEVC clip) in full at load. Snapshots show frames extracted with FFmpeg and never use those copies. Proxies are now served only with --proxy; hyperframes.json media.autoProxy no longer turns them on for snapshots.
* docs: snapshot makes no media proxy unless asked
