Phase 8: the quest book, generated from docs/quests.yaml

- tools/quests.py writes pack/config/ftbquests/quests/ in FTB Quests 2101's
  format (data.snbt, chapters/*.snbt, texts in lang/en_us.snbt) with ids
  derived from the YAML names, so progress survives regeneration. Flexible
  progression, no lock icons, no rewards (Adrian, 2026-11-03). tools/build.py
  runs it.
- docs/quests.yaml: 18 chapters, 74 quests. Getting Started; one chapter per
  zone and the End from a zone template (reach it, catch three of its
  Pokemon, mine its ores, beat its guardian) plus chapter extras (Mire
  Waders, Eyes of Ender, Eternatus); Pokemon Machines; Base and Jobs.
- Node positions: --pull reads them from an FTB Quests folder into the
  layout block (only moved nodes); tools/prism_instance.py pulls from the
  instance before each sync and rebuilds if something moved.
- The pack's own events as hidden advancements (cobblesurvival:events/...),
  granted by QuestEvents: zone reached, guardian beaten, machine filled, End
  boss beaten.
- Self-tests quest_book_loads and quest_events_mark_zones; the guardian and
  furnace tests check their events. Self-tests and island check pass.
