The Agent SDK download notification currently always says: "To use the {agent} Agent, we need to download the {agent} Agent SDK." When models are already available for that agent, the user can also send a message and let the SDK download on use. The notification should communicate that path.
Expected behavior:
- When the agent has models available and its SDK is not downloaded, update the notification text to say the user can click Download or send a message.
- Reactively update the text when model availability changes while the notification is visible.
- Retain the current required-download wording when no models are available.
- Continue to always show the Download action.
