Implement write plan mechanism for string interning and IId object reference tracking. Scan pass now builds pre-computed WriteDuplicateEntry instructions, eliminating hot path IdentityMap lookups and redundant getter calls in the write pass. Update BinarySerializationContext, tracking visit indices and managing write plan array. Refactor ScanInternString and TryTrack methods to record visit indices and build write instructions for all duplicate occurrences. Update write pass logic to consume write plan entries. Add debug validation for scan/write pass order. Update benchmarks and test harness. Set UseGeneratedCode default to false. Improves performance for scenarios with interning and reference tracking.
Introduce JitDisassemblyBenchmark for analyzing JIT-generated x64 assembly of AcBinarySerializer hot paths, accessible via --jitasm. Refactor string interning logic to support per-property and string collection interning, adding IsStringCollectionProperty and ScanStringCollection. Update ScanPass and WriteString for finer-grained control. Remove DEBUG-only CurrentPropertyPath in favor of a more robust property tracking approach. Update usage instructions and clean up related code.
