Copilot 1a1cd853f8 Add wave:term component with direct SSE output + /api/terminput input path (#2974) ... This PR introduces a standalone Tsunami terminal element (`wave:term`) and routes terminal IO outside the normal render/event loop for lower-latency streaming. It adds imperative terminal output (`TermWrite`) over SSE and terminal input/resize delivery over a dedicated `/api/terminput` endpoint. - **Frontend: new `wave:term` element** - Added `tsunami/frontend/src/element/tsunamiterm.tsx`. - Uses `@xterm/xterm` with `@xterm/addon-fit`. - Renders as an outer `<div>` (style/class/ref target), with xterm auto-fit to that container. - Supports ref passthrough on the outer element. - **Frontend: terminal transport wiring** - Registered `wave:term` in `tsunami/frontend/src/vdom.tsx`. - Added SSE listener handling for `termwrite` in `tsunami/frontend/src/model/tsunami-model.tsx`, dispatched to the terminal component via a local custom event. - `onData` and `onResize` now POST directly to `/api/terminput` as JSON payloads: - `id` - `data64` (base64 terminal input) - `termsize` (`rows`, `cols`) for resize updates - **Backend: new terminal IO APIs** - Added `/api/terminput` handler in `tsunami/engine/serverhandlers.go`. - Added protocol types in `tsunami/rpctypes/protocoltypes.go`: - `TermInputPacket`, `TermWritePacket`, `TermSize` - Added engine/client support in `tsunami/engine/clientimpl.go`: - `SendTermWrite(id, data64)` -> emits SSE event `termwrite` - `SetTermInputHandler(...)` and `HandleTermInput(...)` - Exposed app-level APIs in `tsunami/app/defaultclient.go`: - `TermWrite(id, data64) error` - `SetTermInputHandler(func(TermInputPacket))` - **Example usage** ```go app.SetTermInputHandler(func(input app.TermInputPacket) { // input.Id, input.Data64, input.TermSize.Rows/Cols }) _ = app.TermWrite("term1", "SGVsbG8gZnJvbSB0aGUgYmFja2VuZA0K") ``` - **<screenshot>** - Provided screenshot URL: https://github.com/user-attachments/assets/58c92ebb-0a52-43d2-b577-17c9cf92a19c <!-- START COPILOT CODING AGENT TIPS --> --- 💬 We'd love your input!
