holdNoteSet property

Completer<void>? holdNoteSet
getter/setter pair

Mirrors holdSet for the #390 note write: when set, setDeepScanRestoreNoteState blocks on this BEFORE mutating the flag — so a test can prove the controller AWAITS the note write BEFORE it flips the session to OnboardingActive.

Implementation

Completer<void>? holdNoteSet;
