-- Migration 039: Drop FK constraint on saved_recipes.recipe_id.
--
-- In cloud mode the recipe corpus is ATTACHed as a separate database.
-- SQLite FK constraints only resolve against the `main` schema, so
-- `REFERENCES recipes(id)` was always failing for cloud saves (the
-- main.recipes table is empty; all data lives in corpus.recipes).
-- The corpus is read-only and never modified by the app, so cascade-on-delete
-- is meaningless anyway. Remove the constraint without changing any data.
