-- Reset manual_username for all users so the profile sync worker can
-- re-evaluate every active user. Earlier admin Add calls always pinned the
-- username at creation, which permanently excluded those rows from
-- ListForSync. Going forward, only explicit username changes (admin Update
-- via SetUsername) pin the row; sync will be a no-op when the kind:0
-- profile already matches the stored handle.
UPDATE users SET manual_username = 0 WHERE manual_username = 1;
