Summary

• Add a downloadable macOS HydraDB driver with native graph browsing, scoped connections, Cypher editing, supported property filters and export. Reuse the shared Bolt transport without changing PluginKit.
• Preserve sparse export properties beyond the 1,000-entity browser sample. Reject unsupported grid operations and generated SQL DDL; support the filter UI's not-equal operator.
• Requires the unreleased server compatibility branch, tracked in HydraDB issue 297. Grid edits, schema DDL, import, explicit transactions and cluster routing/failover are unavailable.

Paired draft docs: TableProApp/docs#169

Test plan

• Real HydraDB: 13 production-driver checks pass, including numeric not-equal rows/count, parallel relationship identities and sparse 1,002-row export. Python protocol assertions pass. Native TLS accepts the trusted certificate and rejects the untrusted certificate.
• Real Neo4j regression and 45 isolated graph-core tests pass.
• Source generation, touched Swift lint and docs parity pass. Local full app checks remain blocked by Xcode 26.2 RedisReply Sendable errors; CI uses Xcode 27.1. GUI verification remains pending.
• CI is running on the latest commit. No merge or plugin publication is requested.
