Feature
Added subject_role field to distinguish athletes, coaches, celebrities, and characters. VeeFriends characters, Finest Fans celebrities, Content Condors creators, and Dana White backfilled. Set pages now use dynamic labels (e.g., 'Characters in Set' for VeeFriends).
Subject Role Classification
New subject_role column on the players table classifies each subject as athlete (default), coach, celebrity, or character. Backfilled 321 VeeFriends characters, 9 Finest Fans celebrities, 9 Content Condors creators, and 4 Dana White entries. Set detail and athlete detail pages now derive their sidebar and stat labels from the dominant role in the set — VeeFriends shows "Characters in Set" instead of "Athletes in Set". Added glossary entry for Subject Role.
