Based on upstream BetterStructures 2.1.2. All changes below are relative to the original release.

Fixed

PersistentDataContainer for chunk tracking: Replaced isNewChunk flag with PersistentDataContainer to reliably track processed chunks, preventing duplicate structure placement on server restart.
Cross-chunk structure placement: Fixed 5x5 transparent chunk holes by verifying chunk generation before world block access in createPasteBlocks() and assignPedestalMaterial(), ensuring all surrounding chunks are loaded before pasting.

Changed

Async block pasting via FAWE: Migrated block pasting from the WorkloadRunnable frame-splitting system to FAWE asynchronous EditSession, completely eliminating main thread blocking.
    Hard dependency changed from WorldEdit to FastAsyncWorldEdit in plugin.yml.
    FAWE is detected on startup; plugin disables itself if FAWE is not present.
    Removed WorkloadRunnable system; all blocks (including NBT) are now pasted through a single FAWE async EditSession.
    Bedrock checking uses editSession.getBlock() asynchronously.
    Entity spawning and chest filling are deferred to the main thread after async paste completion.
    Removed deprecated createSingleBlockClipboard method from WorldEditUtils.
Parallelized schematic loading: Schematic and module file loading now uses parallelStream(), significantly reducing plugin startup time. Timing logs added for diagnostics.

Added

Chinese localization: Full Chinese language support throughout the codebase.
README: Added project README.

Notes

The config option percentageOfTickUsedForPasting is now obsolete due to the fully async architecture.
