Add support for TTL (Time-To-Live) for inactive peers

🚀 Feature Request

It would be great to have a configurable TTL (Time-To-Live) mechanism for peers in the Wormhole network.

🧠 Motivation

Currently, once a peer connects, it stays registered indefinitely unless explicitly removed. In some use cases, this can lead to a buildup of stale or inactive peers over time. This may impact network cleanliness, memory usage, or overall peer management.

💡 Proposed Solution

Introduce an optional TTL setting for peers. After a peer has been inactive for a configurable amount of time (e.g. X hours), it should be automatically removed from the peer list.

Not cleaning up inactive peers causes entries to appear in the app list that shouldn’t be there.
