Rust Service Plugin Template

This template targets the Component Model-only runtime (runtime.kind = "wasm-component") and exports the yoi:plugin/instance@1.0.0 world.

It demonstrates both authoring surfaces supported by a shared Plugin instance:

• example_echo is an ordinary request/response Tool handler.
• example_ws is a Service ingress handler. The host owns WebSocket receive/reconnect work and dispatches bounded websocket_text events into handle_ingress. The guest replies by returning a websocket_send output command in ServiceOutput; do not run a guest-side recv(timeout) polling loop. The manifest declares host_api.websocket plus a matching [[websocket]] target for the example URL. Enablement grants must explicitly allow the same WebSocket target before the host will send output commands.

Build with cargo component build --release (or the project-specific build command used by your Plugin packaging flow), then run yoi plugin check / yoi plugin pack from the generated Plugin directory.
