worldDL v0.1.0

Added

• Add a LeviLamina 26.51.6 client mod for saving received Bedrock chunks.
• Add local start, save, stop and status commands.
• Write block palettes, biomes and block entities to an uncompressed LevelDB world.
• Add bounded background writes, separate dimension keys and session isolation.
• Add storage tests and an offline .mcworld packaging script.
• Configure air-only Overworld generation for undownloaded terrain.
• Retry the final capture when the write queue is full.
• Add English and Simplified Chinese documentation, contribution guidelines and dependency notices.

Fixed

• Remove the ordinary-mod dependency on the preloaded LeviLamina loader, which prevented WorldDL from loading. Keep the client loader requirement in tooth.json.
