Cryptid Core Co Field Operations

v0.8.0-d — Stage 8d: Locate & Biomes

Added

• /locate structure support for all six buildings (Boat House, Weir, Campsite, Field Station, Abandoned Field Station, Watchtower) via full conversion to the structure system; generation output identical to the old feature placement, rarities preserved via random_spread spacing, minimum separation now guaranteed
• Cartographer trades: Field Station Map (level 4) and Abandoned Station Map (level 5), 13 emeralds + empty map, vanilla treasure-map behavior
• Four registered biomes: Piney Creek Hollow (promoted from the Stage 2 birch injection), Piney Woods, Misty Pine Ridge, Sunken Grove — complete with effects, quiet-woods no-hostile spawn tables, deer variant dispatch, berry patches, and building eligibility (natural overworld placement still pending the TerraBlender/biome injection fix — see STAGE8D_NOTES)

Changed

• Old worlds keep all existing buildings; new chunks generate buildings through the structure system (Option A migration — no world regen)
