feat(scheduler): periodic title+duration dedup (missing-merge tube dupes)

Missing-merge duplicates (same performer + identical normalized title + identical duration-to-the-second) that bulk_dedup misses — tube re-scrapes and cross-tube re-ingests like porn00 pulling a video already present from xnxx (reports 28fe8181/32df33b1). Extracted the proven merge_exact_title_duration logic into app/scheduler/title_duration_dedup.py (script now a thin wrapper), wired a 12h scheduler job (playback-only = what users actually see, GOON_SCHED_TITLE_DEDUP_HOURS). Signal is near-certain (two different videos don't share byte-identical title AND exact duration); no shared performer = not merged (over-match guard). Verified: job registers (jobs=14), backlog currently 0 after the one-shot global merge.
