Mastra Agents Add Ring Signals for Doorbell Events

Mastra agents can now receive Ring doorbell events as notification signals via the new @mastra/ring-signals package, requiring @mastra/core@1.81.0 or later. Each event arrives in the agent's thread with a configurable priority, and the agent can fetch a snapshot or video clip from the Ring API to decide how to respond. Ring signals can also target an existing channel thread, such as iMessage, so alerts reach a shared conversation.
