AI Summary

Fixes a critical crash (SIGSEGV) related to graph replica divergence and enhances performance by optimizing graph loading and exposing new APIs for encoding version management.

Key Highlights

  • Fixes replica SIGSEGV crash when an effect references a non-existent node or edge.
  • Speeds up graph loading by removing full sync from the decoder and using incremental matrix rebuilding.
  • Exports new public APIs (Graph_EncodingVersion, Graph_GetDecoder) for external modules.

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)
