feat: add exploration and crafting systems

Adds two new game systems: Exploration (scouts collect materials from
timed area runs) and Crafting (combine materials into permanent
multipliers). Includes 72 exploration areas, 54 materials, 36 recipes,
and 108 new Codex lore entries. Removes unused characterName requirement
from prestige/transcendence/apotheosis reset flows.
