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")
```
