Harden NBT/packet handling and add defensive checks across multiple protocols and utilities.
- ServerBot: Improved create-state NBT parsing, fill legacy fallbacks, validate skin list entries, and guard loading of saved actions/configs with try/catch and logged warnings.
- LeavesProtocolManager: Treat malformed payloads as rejected (INVALID_PAYLOAD), avoid throwing on decode failures, add safe bytebuf invocation with logging, and a selector description helper.
- REIServerProtocol: Enforce tag types and presence, validate indices and slot bounds, and improve error messages for malformed REI data.
- LitematicaSchematic: Validate schematic metadata (non-empty regions, palette), check region sizes and limit volume to a maximum, and avoid silent failures.
- ServuxLitematicsProtocol: Wrap Litematica paste handling in try/catch, notify player on invalid data, and log warnings.
- LitematicaBitArray: Validate array size/backing storage, prevent oversized backing arrays, and add index bounds checks.
- LitematicaBlockStatePalette: Improve error messaging for invalid palette entries.
- SchematicPlacement: Validate required tags (Schematics/Origin/SubRegion positions), use safe enum-by-ordinal lookup, and guard against null vanilla boxes when streaming chunk positions.
- CommunicationManager: Validate ordinals for rotation/mirror, limit sub-region modification counts, and catch/reject malformed Syncmatica packets with logging.
Overall this commit improves robustness by validating inputs, avoiding unhandled runtime exceptions from malformed or malicious data, and adding informative logs for rejected payloads.
