handoff: mark the overtaken initial-focus section, which still read as live

sylpheed-port pointed out that a newest-first convention protects a top-down
reader while a grep lands mid-document. Both of that section's claims have since
been overtaken -- the disagreement is settled at NEW GAME, and the persistence
question has been run -- and it carried no forward marker.

Kept rather than deleted: it is what the port was told at the time, and a reader
arriving by grep needs to know it was superseded.

+> * *"the sources disagree"* — **settled**. Initial focus on a fresh boot is

+> * *"never once run: whether focus persists"* — **it has been run**. The main menu

 **New, and it is a warning rather than an answer.** `menu-navigation-semantics.md`
 records initial focus as **`TUTORIAL`** (2/2 boots). But `boot_menu.sh`'s own
 closing line says **`NEW GAME`**, and `menu-state-in-memory.md` reaches `EXTRAS` in
