feat: find-all → filter → dedup flow

- addJobs: allows same job on multiple tracks (dedup key = track::id)
- Cross-track copies get composite id (job.id_track) to avoid batch collisions
- dedupeAfterFilter(): after collect, keeps highest-scored copy per URL, marks rest as 'duplicate'
- Called automatically at end of collect phase
