-- v1.19.0 — force-reply correlation for the interactive mood reminder.
-- Maps a bot prompt message to the entry a free-text reply attaches to.
--
-- Idempotent guards (`IF NOT EXISTS`) so a rerun is safe on prod. The
-- semantics are unchanged from the original cut (same table, same columns,
-- same indexes) — v1.19.2 added only the guards.
