Extended the historical-write serializer from Float-only to all five analog types EnsureTagAsync
supports. Captured each type's "ON" buffer live from the native client (sandbox tag per type,
written + captured + deleted):
- The 4-byte value descriptor (C0 10 01 00) is CONSTANT across types — it does not encode the type.
- The value is u32(0) + native-width value, width by the tag's declared type:
Float->float32, Double->double64, Int2->int16, Int4->int32, UInt4->uint32.
HistorianHistoricalWriteProtocol.SerializeAddStreamValuesBuffer now takes the HistorianDataType and
encodes accordingly (unsupported types throw ProtocolEvidenceMissingException). The orchestrator
resolves the type from the tag-info NativeDataTypeDescriptor via MapDataType. Harness capture-write
gained --data-type. Golden-tested against all five live captures + the gated write/read-back test
validated each type end-to-end through the pure-managed SDK; 281 unit tests pass.
