fix(hnsw): synchronize parallel add graph updates (#1873)

Prevent concurrent inserts from dropping neighbor updates by making neighbor-side read-modify-write atomic, keep new points invisible until linking completes, and align lock ordering to remove the TSAN-reported inversion.

fix: make VsagException public inherit from std::exception (#1789)

* fix(resize): ensure size is updated after successful expansion

Move max_capacity_ update to after all expansion operations complete.
This prevents inconsistent state where size is updated but memory
allocation failed in subsequent resize operations.

Fixes resize ordering in:
- HGraph::resize
- GraphDataCell::Resize
- FlattenDataCell::Resize
- ExtraInfoDataCell::Resize
- SparseVectorDataCell::Resize

* fix: make VsagException public inherit from std::exception (#1776)

The class was using private inheritance which prevented catching
VsagException with std::exception handler, breaking standard C++
exception handling patterns.
