Economy Changes/ Bug Fixes — Bitroca Steam update #345753

- 📖 New Codex guide — tap the book icon on the left to learn how everything works: mining & Proof of Break, the Crucible, trading, owning worlds, and the Chain. New players, start here. - 🤝 CIPHER is now a true player marketplace — CIPHER no longer makes or sells its own items. Everything for sale is listed by real players and bought by real players. It's a pure middleman so you can trade with the community even when others are offline — no minted currency, no NPC stock. - 📍 Spawn setter overhaul — spawn points can no longer be punched out and taken. To move your world's spawn, just place a new spawn setter — everyone gets sent back to the atlas and re-enters at the new spot. (Spawn setters are now one-time use.) - 🌍 Fixed the "double world" glitch — no more phantom dropped blocks or a missing CIPHER when you first load into a world.
