Verify Jet Browser startup, native input, DOM agreement, and PNG capture inside a network-isolated WPE WebKit container.

## Good to know before installing

Runs `docker run` (Docker access is root-equivalent on the host) on the digest-pinned image ghcr.io/masakaai/jet-browser@sha256:540a1fec…, pulled from GHCR on first use; the container has no network and only SETUID/SETGID capabilities, but runs with AppArmor and systempaths unconfined and a seccomp profile that allows user-namespace and mount syscalls for WebKit's bubblewrap sandbox; the tool takes no arguments and loads only a built-in local test page.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install jet-browser
```

2. Said no? Turn it on later:

```bash
hermes plugins enable jet-browser
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
