RocheDB v0.6.0: Locality Validation, Topology Remapping, and Safer Query Boundaries

I released RocheDB v0.6.0. Release: https://github.com/puffball1567/rochedb/releases/tag/v0.6.0 RocheDB is a ring-oriented NoSQL document and vector database written in Nim. The project is still a technical preview, but v0.6.0 is an important release because it moves more of the project from concept and happy-path demos toward measurable locality behavior. The main theme of this release is: If data locality is part of the database model, it should be tested as an invariant, not only described as an idea. What Changed v0.6.0 focuses on five areas: safer read filters; topology remapping foundations; locality validation workloads; easier operational configuration; practical use-case recipes. The release adds typed RocheFilterBuilder helpers so applications can build read filters without string-concatenating JSON. It also adds topology remapping primitives: explicit arc tables; weighted arcs; deterministic virtual arcs; topology validation; remapFraction. These
