Phase 9: crafted summons for the legendaries

Adrian, 2026-11-09: legendaries, mythicals, Ultra Beasts and Paradox Pokemon
come from crafted summons. 22 Sigils (Naganadel evolves from Poipole), one
item told apart by custom data, from world/summons.json through
tools/summons.py: late-game recipes in three tiers (Lv 70, 80, 90), each used
in a fitting zone. A summoned legend fights as a boss (area attacks by level
and type, arena 32, the Guardian's Ward) but can be caught; on capture it
loses every boss mark. One at a time within 96 blocks.

Quest book: a Legends chapter, one quest per Sigil (97 quests). JEI lists each
Sigil as its own item, and Island Drops says where a legend is summoned; drops
Cobblemon names but doesn't have (Ho-Oh's Sacred Ash) get no slot.

Self-tests every_implemented_pokemon_is_obtainable (spawn, fossil or Sigil for
every implemented species) and sigil_summons_a_catchable_legend. Self-tests
and the island check pass.
