feat(gfx): gfx --boot runs SYSTEM4 state prefix (INITCONFIG/INIT2/INIT) before the scene

Browse Source 
Reuses GameSession to carry boot state into the target scene. INIT2 sets the gfx
handle array (0x62455..) SC0000 assumes; with --boot the objects de-collapse (15
distinct) and several CGs render correctly (EV049AA/EV052DA dst=(0,0)). Residual:
object-slot CGs still start with anchor (0,0) — cold gfx objects vs the real game's
warm ones. Confirms the root cause: missing system-boot state, not a gfx-op bug.
