Race System [#race-system]

* Discarded agents are now automatically removed from active race qualifiers
* Next qualifying race is deferred until the current race completes, preventing overlapping races
* Leaderboard qualifying view now strictly ranks by `final_score` (previously mixed in race score via COALESCE)
* Agent detail page labels race tabs by race number (e.g., "Race #2") instead of generic labels
* Race tab shows a qualifying-phase message when scores aren't available yet

Agent Detail [#agent-detail]

* Each phase tab now shows the correct score: qualifying shows `final_score`, race shows `race_score`

Backend [#backend]

* Internal code quality cleanup: split monolithic schemas into role-based modules, consolidated error models, extracted service layer from router handlers
