Anti-cheat off, weapon sets 6-7 in hero files

- The game's cheater detection killed the hero ("Hase!") whenever its
  protected stat mirror was stale; the mirror is now refreshed from the hero
  whenever it is unlocked, stream checks never punish, loadHero no longer
  sets the cheater flag (docs/anticheat.md).
- saveHero wrote the items of weapon sets 1-5 only: its loop runs over all 7
  sets, so sets 6-7 survive a world loading the hero from the hero file.

+## Quest book: all quests, unknown ones as "???" (2026-10-25)
+
+Request: every quest appears in the quest book; quests not yet activated show
+as "???", so a player knows how many quests an area holds without being told
+where they are. Notes: the quest table (g_quests 0xaa9e98, 0x124 per quest,
+game/engine/quests.h) lists all quests of the campaign, including the generic
+repeatable ones (ids 2600..3599, cloned by Quest_End) and DQ_ dynamic quests;
+which of them count for an area, and how the book groups by area, is still to
+be measured.
