fix(goLive): stream demux directly instead of spool-to-file (empty screen share)

Root cause of 'tile appears but content empty': demux() spooled the live NUT/H264 input to a temp file and awaited stream 'finish' — but the merge ffmpeg output never ends during playback, so demux deadlocked, no probe, no transcode, 0 frames sent. - Demuxer: pipe input straight into ffmpeg stdin (-i pipe:0), parse NAL frames live from stdout; parse video metadata from ffmpeg stderr with a 1.5s race (fall back to H264 defaults). No spool, no await-end. - screenShareController: pass width/height/frameRate (1280x720@30) to playStream — matches the prepareStream encode settings, so setVideoAttributes gets real dimensions even when ffmpeg can't report metadata on an open pipe. - Add tests/golive-demux-live-e2e.ts: proves frames flow while input is still open (regression test for the deadlock).
