T8b949e/**

* A switch-aware [DiscoveryDao] that resolves the active database on every call instead of pinning the one that was

* current at injection time. This is what Koin hands to `feature:discovery` consumers (ViewModels and the scan engine),

* which hold their DAO for their whole lifetime:

* - Flow methods re-latch through [DatabaseProvider.observeCurrentDb], so an open discovery screen follows a device/DB

* switch and recovers from a wedged active Room pool.

* - Suspend methods go through [DatabaseProvider.withDb], so writes register with the cross-transport merge drain

* barrier (a mid-scan merge can't snapshot-then-retire the DB underneath an in-flight session write). A callback is

* never replayed after it starts, so higher layers must make any retry policy explicit where idempotency is known.

*

* `withDb` can return null while no database is available. Collection reads use empty defaults, count reads return

* zero, and operations that require a created row retain non-null checks so callers cannot proceed with an invalid id.
