Zones now unlock in strict linear order. Each zone requires both the
final boss AND the final quest of the previous zone to be completed:
Verdant Vale → Shattered Ruins (forest_giant + ancient_ruins)
Shattered Ruins → Frozen Peaks (elder_dragon + dragon_lair)
Frozen Peaks → Shadow Marshes (void_titan + storm_citadel)
Shadow Marshes → Volcanic Depths (mud_kraken + plague_ruins)
Volcanic Depths → Astral Void (phoenix_lord + the_forge)
- Zone type gains `unlockQuestId` field alongside `unlockBossId`
- boss.ts checks both conditions before unlocking zone on boss defeat
- tick.ts checks both conditions and unlocks zones + first boss on
quest completion if the boss condition is already met
- GameContext optimistic update also respects dual-condition logic

using both conditions, reverting incorrectly-unlocked saves
