/**
 * Pre-flight: verify that the SQLite adapter loads and a writable DB can be
 * opened.
 *
 * Called before binding the port so a broken native build fails loudly with
 * a helpful hint instead of crashing later when the first WS connection
 * arrives.
 *
 * Implementation note: we test by opening the *real* target path. Opening a
 * tmpfile would only verify that the native module loads, not that the
 * config dir is writable. Since `open()` already creates the file/dir
 * idempotently, this is safe to call repeatedly.
