Subject: [PATCH] fix(recording): avoid doubled mic audio on macOS system+mic
 captures

On macOS the system-audio capture already contains the mic, so the recording embeds a full system+mic mix. The fallback also added the separate mic sidecar, doubling the mic into an echo. Use the embedded mix alone. Fixes #628.
