Phase 9: safe start island, better quest book, every useful item obtainable

- Button Isle is peaceful: wild Pokémon only fight a player who hit them first
  (tuning/server.json peaceful_zones); its apricorns and coal make Poké Balls
  (4 apricorns + coal or charcoal), and the world report checks it has enough.
- Quest book: no boilerplate; each zone page says what is particular to it, and
  every zone that needs gear or a field move to be safe has its own quest. New
  page on the bigger mods (Cold Sweat, Fight or Flight, Cobblebase, breeding,
  veins, shared loot, maps and info).
- The Mire's poison stops 10 blocks below the surface.
- Player battles never cost a Pokémon (CobbleHardcoreMon config, mixins, and the
  companion mod's own permadeath).
- tools/item_audit.py: every item with a use has a source on the island; new
  sources for the gaps it found (species additions, three recipes).
