- New regression test `webm-transparency`: minimal transparent composition
rendered to WebM, validates VP9 codec and visual quality at 100
checkpoints against golden baseline
- Extend regression harness: `renderConfig.format` field ("mp4" | "webm"),
format-aware output paths and snapshot filenames
- Fix `extractMonoPcm16` to gracefully handle videos without audio
streams (WebM without audio was throwing instead of returning empty)
- Unit tests for `getEncoderPreset()`: VP9/yuva420p for WebM,
h264/yuv420p for MP4, preset mapping, quality preservation
