-- v1.15.0 — cycle symptom taxonomy.
--
-- Clones the mood-tag trio (0101): a global Category -> Symptom catalog
-- plus a per-day-log join. `CycleSymptom` additionally carries
-- `user_id` + `label_encrypted` so a future release can mint per-user
-- custom symptoms; v1.15.0 ships seeded-catalogue-only.
--
-- `label_key` columns carry an i18n message key (resolved client-side
-- against all six locales) rather than a hard-coded label, so the seeded
-- catalog renders localised everywhere. The seed at the bottom uses
-- deterministic ids + ON CONFLICT DO NOTHING on `key` so re-running is a
-- no-op (idempotent).
--
-- Reversibility (down):
--   DROP TABLE IF EXISTS "cycle_symptom_links";
--   DROP TABLE IF EXISTS "cycle_symptoms";
--   DROP TABLE IF EXISTS "cycle_symptom_categories";
