atomr-agents-coding-cli-harness-web 0.21.0

# atomr-agents-coding-cli-harness-web

Axum + embedded SPA companion for the coding-cli harness.

## Run it

```bash
cargo run -p atomr-agents-coding-cli-harness-web
# default bind: 127.0.0.1:7300
```

Open `http://127.0.0.1:7300/` to see the SPA. Browse vendors, kick off
headless runs (live SSE event log), or open an interactive xterm.js
session against a tmux-wrapped CLI process.

## WebSocket protocol

* **Server → client**: binary frames carry raw PTY bytes (UTF-8 ANSI).
* **Client → server**:
  * Binary frame = stdin bytes (typed keys, paste).
  * Text frame `{"kind":"resize","cols":120,"rows":32}` resizes the PTY.

Run on port 7300 (next slot after deep-research's 7200).
