Add remote_session field to Go, Node, Python, and .NET SDKs

Expose per-session remote behavior control (Off/Export/On) in all
remaining SDK languages, matching the Rust implementation. Each SDK
adds the field to SessionConfig and ResumeSessionConfig, wires it
into the JSON-RPC create/resume payloads, and exports the type.
