Zova v0.20.0

Highlights

Makes application-defined relationships first-class across Zova records, objects, chunks, vectors, entities, facts, concepts, and external IDs.

What's changed

• Added named graph storage with application-provided stable node IDs and typed target references.
• Added graph, node, and directed-edge CRUD APIs.
• Added deterministic incoming/outgoing neighbor queries, degree queries, and bounded breadth-first traversal.
• Added SQL-native graph neighbor and walk virtual tables.
• Added C ABI, Rust, Go, and Python graph APIs.
• Added graph CLI inspection plus backup, compact, restore, check, doctor, and salvage integration.
• Added distribution publishing support.

Compatibility

• Bumps the experimental .zova format to 4 for required graph schema.
• Graphs are local, embedded, and SQLite-backed; this release does not introduce Cypher/GQL or a separate graph server.
