Zenoh reference connector

A third concrete connector instantiating the framework’s contracts. This parent feature :satisfies: Connector framework (FEAT_0030); its three capability clusters — pub/sub (Zenoh pub/sub (FEAT_0043)), queries (Zenoh queries (FEAT_0044)), and session topology and health (Zenoh session topology and ... (FEAT_0045)) — each :satisfies: it, on their own pages (see the toctree).

A third concrete connector instantiating the framework’s contracts: zenoh-backed plugin and gateway with bidirectional pub/sub and queries. The session topology is configurable between peer and client modes; reconnect is delegated to the Zenoh session itself (stack-internal posture mirroring Stack-internal-reconnect co... (REQ_0235)). Queries are exposed via concrete methods on ZenohConnector only — the shared Connector trait is not modified. The gateway owns one zenoh::Session and runs Zenoh’s async callbacks on a tokio sidecar contained inside taktora-connector-zenoh. Linux, macOS, and Windows are supported host operating systems.
