v0.0.8

Fixes three bugs found in a full code review. Critical: after a dry-run pass, turning dry-run off never processed anything because the queue's duplicate check blocked every re-enqueue; skip verdicts are now retryable (except the expensive not-smaller verdict), so config changes and going live work as expected. Also fixes truncated ffmpeg output in the async process runner (could spuriously fail the VMAF gate) and the disk-space check inspecting the root filesystem instead of the media mount on Linux.
