-- For each user past season 2 with no season-2 row yet, infer which sun/moon
-- route they actually played from their cleared quests in user_quests, and
-- insert the matching (season=2, route=X) row. Heals players who progressed
-- past season 2 before per-scene RecordSeasonRoute existed (commit 9a2cc92).
--
-- Quest-ID ranges per route (from master_data/EntityMMainQuestSequenceTable.json):
--   Route 2 (sun/moon variant A): quests 301..370
--   Route 3 (sun/moon variant B): quests 401..470
--
-- The NOT EXISTS clause matches on (user, season) regardless of route, so any
-- existing real RecordSeasonRoute write is preserved verbatim.

-- Rule 1: user has cleared a route-3 quest -> they picked variant B.
