Remap IDs

1.2.1

Fixed

• Tag remapping crash on Forge/Fabric 1.20.1 - TagLoaderMixin was injecting into loadAndBuild(), which returns resolved Holder.Reference objects, causing a ClassCastException. Now correctly targets load(), which returns raw EntryWithSource entries. Also fixed on Fabric 1.20.1 where the same latent bug existed.
• Forge world migration only handled remapids: namespace - ForgeRegistryEvents passed the mod's own ID to getMappings(), so MissingMappingsEvent only caught missing entries with namespace remapids:*. Now collects all source namespaces from the remap config and queries each one. This fixes remaps like create:brass_block → minecraft:copper_block being silently ignored when Create is removed.
• Forge registry lookups could cross-contaminate types - ForgeRegistryMixin looped through all registry types (block, item, fluid, entity_type) for every ForgeRegistry.getValue() call, so an item-only remap could incorrectly redirect a block registry lookup. Now determines the specific registry type from the ForgeRegistry instance and only checks that type.
• Removed leftover debug logging on Forge - The Forge RecipeManagerMixin had LOGGER.info() calls for golden_apple recipe debugging and verbose per-invocation logging left from development. Cleaned up to match the other loaders' LOGGER.debug() level.
• JsonRemapper.rewriteCount thread safety - Changed from a plain int to AtomicInteger to prevent potential race conditions in the rewrite counter.
