Subject: feat: voice-over recording into the timeline

MediaRecorder mic capture (defensive mimeType picking, permission/no-mic
toasts) with elapsed display in the timeline toolbar. Stop produces an
audio asset and inserts it at the playhead on an audio track as ONE
BatchCommand undo step, freeze-frame precedent. voice-over action
registered, no default keybinding. 20 tests; smoke-tested in Chromium
with a fake mic end to end.
