World Mirror

Added

• Xaero's World Map Overlay: Render World Mirror status fills and merged boundaries directly on Xaero's World Map screen.
• Added a PowerShell script helper Get-LatestXaerosWorldMap.ps1 for downloading the latest Xaero's World Map jar for development/testing.
• Customizable Xaero overlay settings: toggle overlay, configure overlay refresh rate, and maximum visible cells limit.

Changed

• Version bump: 0.2.1 → 0.2.2.
• Updated the Minecraft/Fabric dependency set to 26.2, Fabric Loader 0.19.3, Fabric API 0.152.2+26.2, ModMenu 20.0.0-beta.3, LibGUI 17.0.0+26.2, and Cloth Config 26.2.155.
• Reduced routine lifecycle, capture, export, migration, and world-structure logs from info to debug so normal gameplay chat/log output is quieter.
• Removed obsolete chest/debug mixins and centralized block-entity/container NBT handling in BlockEntityNbtSupport.
• Chunk Map Optimizations: Introduced ChunkStatusCache and ChunkStatusSnapshot to cache status data, reducing rendering and database query overhead on both the built-in chunk map and Xaero's overlay.
• Added merged boundary segment rendering to the built-in chunk map, reducing drawing calls when zoomed out.
• Extracted SQLite native drivers isolation for stable read-only status loading.

Fixed

• Container block entities are no longer overwritten with empty Items data when a chunk is recaptured or exported over an existing local chunk. Previously captured or locally written non-empty item lists are preserved when the latest client-side block entity snapshot is empty.
• Container overlays are snapshotted when an export is deferred or running in the background, preventing later cache cleanup from dropping item data before the writer reaches the chunk.
• Default container titles such as container.chest and container.chestDouble are no longer written as CustomName, and old default-name compounds are stripped when chunks are merged.
• Double chest item ordering now follows vanilla's ChestType.RIGHT == FIRST combiner order for both full inventory packets and later single-slot updates, preventing large chest halves from being swapped or partially written.
• Chunk serialization now uses Minecraft's SerializableChunkData path, preserving available section light data (BlockLight / SkyLight), blending data, retrogen, post-processing, filtered heightmaps, and other vanilla chunk serialization fields that the client currently has.
• The download toggle keybinding now uses the P keysym instead of a raw scancode.
• Ported 26.2 client API usages for screen switching, HUD-hidden checks, and flat world preset lookup.
