* Harden serializer deserialization bounds

* Finalize Unix serializer hardening

Validate object types before parsing and release owned objects on failure.
Enforce nesting limits through shared serialization entry points.

Mirror read/write size limits and reject embedded NULs while preserving
the wire format. Add regression tests for bounds, types, and cleanup.

Validated Linux self-tests, C++03 platform tests, and ASan/UBSan with leak
detection.
