v0.77.1

Fixed

• Missing reminders.pushed_at column after database rebuild: migration 57 rebuilt the reminders table without carrying over the pushed_at column added in migration 54, causing PushScheduler to fail with no such column: r.pushed_at on every fresh install or update. A new migration restores the column. (Fixes #393)
• Schema-test export out of sync: the node:sqlite-synchronized schema export used by tests had stopped at migration 61, so schema tests applying the exported migrations never picked up the restored reminders.pushed_at column.
