1.0.6

Multi-File Accumulation: Multiple datapack files can now contribute attributes to the same item. Previously, the last file loaded would overwrite all others. Now entries from all files are merged together.
ListTag Index Navigation: NBT condition paths now support numeric indices to access elements inside list tags (e.g., enchantments.0.id).
not_equals returns true on missing paths: The not_equals operator now correctly returns true when the NBT path doesn't exist on the item, matching the intuitive "this value is not X" behavior.

Villager Trade Quality Template Mutation: Fixed a critical bug where applying quality to a villager trade would permanently modify the trade offer template, preventing re-rolls on future trades. Quality is now only applied via deferred inventory scan.
Network Buffer Desync (Forge): Fixed packet encode/decode that could desync when items with null registry IDs were included, causing all subsequent data in the packet to be corrupted.
Container Close Inventory Scan: The container close event now correctly skips the player's own inventory menu, preventing unnecessary quality re-processing when simply closing the inventory screen.
Regex Pattern Safety: Added PatternSyntaxException catch for the matches_regex NBT operator, preventing server crashes from malformed regex patterns in datapacks.
Long Precision in Quality Values: Fixed quality system NBT writing to properly distinguish between int, long, and double values, preventing precision loss for large numbers.
Null NBT Condition Serialization (Forge): Fixed network packet encoding to correctly handle null NBT condition values using a sentinel, preventing deserialization errors on the client.

Thread Safety (Forge): All attribute maps now use ConcurrentHashMap and volatile instance fields, preventing potential race conditions during reload.
Debug Logging Optimization: Changed all hot-path logging from info to debug level across both versions, reducing log spam during normal gameplay.
Removed Dead Code (Forge): Cleaned up unused handleCuriosAttributes() method and related imports.
