Claude: integrate status

**Describe the feature**

Claude Code has a somewhat notorious (-ly bad) uptime. `abtop` could proactively check on the status page (https://status.claude.com/api/v2/status.json) to monitor for active incidents. Potentially even _on_ retries / errors if that's a thing detectable from the hooks.

**Use case**

`abtop` is currently the one-stop-shop for the status of my CC sessions. Seeing an open status incident for CC would be helpful and likely easy to implement.

**Additional context**

This could be simply rendered into the same place as the "Claude Peak Hours" maybe also with brackets indicating e.g. since when the issues has been open. Just a different color and icon.

Start by locating where abtop renders the "Claude Peak Hours" information and review the Claude status endpoint at https://status.claude.com/api/v2/status.json. Done means active Claude incidents are fetched and shown in that area with an appropriate indicator, including when an incident began if that data is available.
