RunOnce now reads the user's mode (GetAutoSummarize) at the start of each pass:
- Auto (unchanged): summarize every unseen video.
- Manual: still UpsertVideo for every candidate (discovery — the user sees new
videos in the list), but skip ProcessNewVideo unless the video is queued
(RequestedVideoIDs). A queued video is summarized, then its flag is cleared
(ClearSummarizeRequested) so it is not re-processed and the UI drops "Queued".
New Stats.SkippedManual counts discovered-but-unqueued videos. The VideoStore
port gains the three methods; the existing auto-mode tests set auto:true.
