-- Refresh tokens (owned by the auth worker). Only a SHA-256 hash of each token is
-- stored, never the raw value. Single-use: redeeming deletes the row and a new
-- token is issued in its place (rotation). platform/platform_id are kept so the
-- access token can be re-minted on refresh. Kept in sync with REFRESH_SCHEMA_DDL
-- in src/refresh-db.ts.
