The exporter test vector labels are hex-encoded strings used AS-IS (as string labels), not decoded from hex to bytes. The test was incorrectly hex-decoding the label before passing it. Also removed the now-unused expandWithLabelRaw and ByteArray mlsExporter overloads since the string-based API is correct for all MLS usage. Test results: 33/41 passing (80%). https://claude.ai/code/session_01NocQDWj2Y92FugjfgazzL3
