/**
 * AutofillNavRepository carries the one-shot "open the new-entry editor" request
 * from the autofill picker through MainActivity to PeachAppNavHost. The NavHost
 * consumes the request as part of its LaunchedEffect, so the repository must
 * surface the request exactly once before clearing — re-firing the LockScreen
 * post-unlock branch after the consume is what made the new-entry redirect
 * land on the vault list instead of the editor.
