-- Move schema-v5 per-turn and session-cadence fields into the detail tables.
--
-- Production D1 `events` is at 96 columns and D1 caps tables at 100 columns,
-- so migration 0005's ALTER TABLE events additions (turn_index, turn timings,
-- turn_success, session hour/cadence fields, ...) can never apply there:
-- `too many columns on sqlite_altertab_events`. The worker filters inserts by
-- the live column set, so these client-sent fields were silently dropped.
-- The detail tables have plenty of headroom, so record the fields there.
