Subject: [PATCH] fix(persist): guard markSaved against in-flight edits

markSaved cleared dirty unconditionally, so an edit made while a save
was in flight had its dirty flag wiped and its follow-up save dropped.
Only clear dirty when the book reference is unchanged since the save
started (immutable updates give a fresh reference per edit).
