Detailed Description

Per-rank JSON serializer implementing the SerializerBase interface.

Unit Test Coverage (test_Serializer.cpp, MPI np=1,2,4)

• Scalar round-trip: WriteInt/ReadInt, WriteIndex/ReadIndex, WriteReal/ReadReal, WriteString/ReadString
• Vector round-trip: WriteRealVector, WriteIndexVector, WriteRowsizeVector
• uint8 array: with and without codec (base64 + zlib)
• Path operations: CreatePath, GoToPath, GetCurrentPath, ListCurrentPath
• Shared pointer deduplication: WriteSharedIndexVector / ReadSharedIndexVector

Not Yet Tested

• WriteSharedRowsizeVector / ReadSharedRowsizeVector
• WriteIndexVectorPerRank
• SetDeflateLevel impact verification
• Error handling (nonexistent file, duplicate paths)
