Conservative Chrome tab cleanup with in-process observation and browser-call leases.

## Good to know before installing

Runs a background thread inside Hermes that proxies your local Chrome DevTools port (127.0.0.1:9222 → 127.0.0.1:9223, loopback only, you must point browser.cdp_url at it), injects a focus/activity listener into every Chrome page, rewrites browser_exec session names to a per-profile namespace, and a cron script you schedule auto-closes idle, duplicate and blank tabs (including tabs with unsaved text).

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 chrome-tab-watchdog
```

2. Said no? Turn it on later:

```bash
hermes plugins enable chrome-tab-watchdog
```

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
