AI Summary

This maintenance release focuses on stability and performance. It fixes a crash in effects when nodes or edges are missing and optimizes graph loading by removing full syncs from the decoder. It also exposes new public APIs for external modules to control graph serialization versions.

Key Highlights

Fixes SIGSEGV crash on replica divergence
Performance improvement by removing full sync from decoder
Exports new public APIs for graph serialization

New Features

Export Graph_EncodingVersion and Graph_GetDecoder public APIs

Full Release Notes

## What's Changed

### Bug Fixes
* fix(effects): stop replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence - replicas no longer crash when an effect references a node or edge that no longer exists locally; the mismatch is now detected and triggers a full resync instead (#2581)

### Performance
* remove full sync from decoder - transpose matrices are rebuilt incrementally as delta-matrix components are set during RDB decoding instead of forcing a full sync at the end, speeding up loading of persisted graphs (#2584)

### Improvements
* serializers: export Graph_EncodingVersion and Graph_GetDecoder - new public APIs let external modules (e.g. graph-offloading) stamp dumps with their encoding version and select the matching decoder on load (#2552)
