AI Summary

This release focuses on stability and performance. It fixes a critical crash bug in replica handling during divergence and optimizes graph loading by removing unnecessary full syncs during decoding. It also exposes new APIs for external modules to manage encoding versions.

Key Highlights

Fixed replica SIGSEGV on divergence to prevent crashes
Improved performance by removing full sync from the decoder
New public APIs for encoding version management

New Features

Export Graph_EncodingVersion and 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)
