Fix RS2 disk + SS shulker data loss: use in-memory API, not .dat files
ROOT CAUSE for both: - RS2: We removed dataStorage.save() to avoid fastasyncworldsave crash, but then read the .dat file which had stale data. Disks appeared empty because the file didn't contain the latest in-memory state. - SS: getOrCreateStorageContents() could create empty content if the data wasn't loaded yet for that UUID. FIX RS2: - Save: Use SavedData.save(CompoundTag, Provider) which serializes from MEMORY, not disk. No file I/O, no fastasyncworldsave conflict. - Restore: Decode entries via RS2's codec (reflection on getMapCodec) and inject via repo.set(). Falls back to direct NBT injection if codec fails. - Removed dead code: getRS2DataFile, injectRS2EntryIntoNbt FIX SS: - Already using StackStorageWrapper.fromStack() API for UUID extraction (DataComponent-based, not CustomData). This was fixed in previous commit. If data still missing, the save() logging will show which UUIDs fail to find in ItemContentsStorage. Vyrriox
