 /**
  * v33 → v34: add `config_entry`, the account-scoped home of every `sync = true` setting.
  *
  * Pure addition. Nothing is backfilled from the DataStore values the settings live in today: the
  * app is not released, so losing current dev/test settings is the cheaper side of the trade — a
  * decision ADR-004 marks as expiring at the first production release.
  *
  * The migration is not optional busywork. On debuggable hosts `getRoomDatabase` still ends in
  * `fallbackToDestructiveMigration(dropAllTables = true)`, so a missing 33 → 34 path does not fail
  * loudly there — it silently drops every table on the first launch after the upgrade. Release
  * builds pass `allowDestructiveMigration = false` and crash on open instead; either way a hole in
  * the chain costs the local database. See `docs/architecture/persistence.md` → "Room schema
  * versioning".
  *
  * The DDL is the one Room generates for `ConfigEntryEntity`; keep the two in step or Room's schema
  * validation fails at open time.
