ffmpeg.ts:
- Replace exec() with spawn() for ffmpeg/ffprobe — no shell interpreter,
no injection risk from filenames with special characters
- Filter invalid ranges in computeIdleSections() after clamping to video
bounds (handles timestamps exceeding video duration)
- Use path.basename() for timer IDs instead of split('/') for Windows compat
executor.ts:
- Use try/finally around VM execution so execution timestamps are recorded
even when code throws — the execution still occupied real time that should
not be sped up in the demo video
- Snapshot recordingStartedAt before try to avoid race if stopRecording()
is called inside the same execute() clearing the field
