AI Summary

This release addresses a critical crash (SIGSEGV) in replicas when diverging from the master by handling missing nodes and edges gracefully. Performance is improved by rebuilding matrices incrementally during decoding. Additionally, new public APIs are exposed for graph encoding versioning.

Key Highlights

Fixes replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence
Incremental matrix rebuilding for faster RDB decoding
New public APIs for graph encoding versioning

New Features

Export Graph_EncodingVersion and Graph_GetDecoder 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)
