Replace plain TCP JSON-lines connections with bounded loopback WebSockets using the required runa-debug subprotocol. Keep single-threaded image dispatch and stdio framing unchanged.
Broadcast coalesced, non-destructive image_changed invalidations after successful mutations. Update the REPL client and automatically refresh VS Code actor trees and open inspectors, preserving request correlation and connection-session isolation.
Validate negotiation, message limits and fragmentation, multi-client notifications, real REPL interoperability, and automatic mailbox/lifecycle/failure inspection in a VS Code extension host.
BREAKING CHANGE: the network endpoint now accepts only runa-debug WebSockets at the root path, not plain TCP JSON Lines. Rust network integrations must use WebSocketClient and serve_websocket. Request/response DTOs remain protocol v3; stdio is unchanged.

Add runa-client for launching the JSON-lines server as a child process and exchanging bounded, correlated protocol requests. Validate response versions and request IDs, expose graceful shutdown, and test the client against the real server process. Clarify that VS Code is planned to use an authenticated network connection to the same live image, while stdio serves local child-process integrations and actors remain in the image.
