0.18.3: grouped clip tracks render, playhead is a snap magnet

Browse Source 
- Fix mask-preview / frame-export dropping any group whose children
  are clip tracks. render.ts's old group branch only pulled Layer
  children out of group.childIds; new drawTrackGroup walks both
  layer AND clip-track ids and still applies group-local masks to
  the composite. Same fix mirrored into the HTML export runtime in
  exportPlayer.ts.
- Snapping magnet for the playhead: snapTime now includes
  store.playhead in its candidate list by default. Clip drags, trim
  handles, keyframe drags, marker drags and in/out brackets stick
  to the needle when snap is on. Scrub handlers pass
  ignorePlayhead:true so the needle doesn't stick to its own prior
  position during a scrub.
- Clip trim handles derive the snapped edge first and back out to
  trimStart/trimEnd, so the edge lands exactly on the magnet.
