Chapter 1 sigil retiming; Dart joins in the excavations arc

Maya's Spikes moves from the stone plateau to the broken-temple entry, so the early fights play out before Spikes arrives instead of the rest of the chapter leaning on it from the moment you get Maya. Grey's Gust pulls in from the caves to the stone plateau, and Grey's Draft pulls in from the temple dining hall to the caves, so Grey's wind kit reads as useful through the middle of the chapter rather than arriving late. Tara's Adamant gets pulled out of chapter 1 entirely.

Dart now joins the party during the excavations arc, on the together-again beat, instead of waiting until later. The leaving-excavations scene used to lock you to a fixed three heroes going forward; the required-hero list is now cleared, so you pick any three from the roster you have at that point.
