MediaRecorder/captureStream kept crashing the Chrome renderer
(STATUS_BREAKPOINT). Video is now encoded offline with VideoEncoder
(VP9 with VP8 fallback) and muxed by a dependency-free EBML/Matroska
writer. Adds precise export controls: video fps (24/30/60), exact
length (1-8 loops or 5-60s), and a GIF loop-forever/play-once toggle.

Replace realtime captureStream(60) with manual captureStream(0) +
requestFrame at 30fps, suspend the live render loop during export,
prefer VP8, and cap bitrate to avoid STATUS_BREAKPOINT tab crashes.
