// Standalone one-shot migration from the single-user schema to the multi-user
// schema. Idempotent (safe to run repeatedly). Run it once on an existing
// single-user install before (or alongside) the first boot of the multi-user
// server — the server runs the same migration at boot too, so this script is
// mainly a convenience for migrating without starting the server.
